Installing the Router

Installing the Router

This chapter provides the following procedures for installing the router at your site, installing power supplies, making all external cable connections, and applying power:

An optional rack-mount kit is available for mounting the router in a standard 19-inch-wide equipment rack with four unobstructed outer rails. This kit is suitable for use with other rack types, such as Telco-type equipment racks. If you plan to use an equipment shelf or other type of rack installation, review the guidelines in the section "Equipment Racks" in the chapter "Preparing for Installation" before proceeding. If you are not rack-mounting the router, proceed to "General Installation" later in this chapter.

Caution Before installing the chassis in a rack or wiring closet, read the section "Safety Recommendations" in the chapter "Preparing for Installation" to familiarize yourself with the proper site and environmental conditions. Failure to read and follow these guidelines could lead to an unsuccessful installation and possible damage to the system and components.


Rack-Mounting the Router

The procedures for rack-mounting the router are included in the configuration note Cisco 7000 and Cisco 7507 Rack-Mount Kit Installation Instructions (Document Number 78-1058-xx, where xx is the latest version). A printed copy of this configuration note is packaged with the rack-mount kit that shipped with your router, and it is also available on Cisco Connection Documentation CD-ROM. Follow the procedures included in this configuration note to install your Cisco 7507 in a rack. If you do not plan to rack-mount your chassis, proceed to the following section "General Installation."


General Installation

The router should already be in the area where you will install it, and your installation location should already be determined; if not, refer to the section "Site Requirements" in the chapter "Preparing for Installation."

When installing the router on a table or floor, ensure that you have planned a clean, safe location for the chassis and have considered the following:

Warning The AC power supply for the Cisco 7000 and Cisco 7010 has double pole/neutral fusing.

fig_15.gif Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface processors, or by the plastic panels on the front of the chassis. These handles were not designed to support the weight of the chassis.


Installing Power Supplies

You will install one or two, AC-input or DC-input power supplies in the upper and lower power supply bays in the rear of the chassis. Always install the first power supply in the lower power supply bay and the second, if any, in the upper bay. The power supply switch also has a locking device. (See Figure 3-1.) When the switch is in the on (|) position, the locking device extends into a slot in the chassis to prevent it from being removed accidentally or from falling out of the chassis.

Figure 3-1 Power Supply Interlock (AC-Input Power Supply Shown)

Before proceeding, ensure that you have sufficient working space (three to four feet) behind the chassis and that access to the power supply bays is not blocked by an equipment rack power strip or cables from other equipment. If cables from other equipment are in the way, move them aside and temporarily secure them with tie wraps before proceeding. Keep in mind that cables that block access to the bays may also block the power supply LEDs from view. If a power strip or other rack fixture is in the way, you might need to loosen the chassis ears from the equipment rack and carefully push the chassis out of the rack until you can maneuver each power supply into a bay.

Note The power strips provided in some equipment racks might partially block access to the chassis power supply bay. If so, you will have to slide the front of the chassis out of the rack far enough to allow the power supplies to clear the power strip. Steps for doing so are included in the procedures that follow.


Tools Required

You need the following tools to complete this procedure:

Before beginning the power supply installation, note the type of installation screws on all power supplies and check the area around the power supply bays to determine which tools you will need.


Accessing the Bays

This section describes how to proceed if your system is installed in an equipment rack and you do not have clear access to both power supply bays. If the chassis is not in a rack, or if you already have clear access to the power supply bays, proceed to the following section "Inserting Power Supplies."

Warning To prevent bodily injury when mounting or servicing this unit in a rack, you must take special precautions to ensure that the system remains stable. The following guidelines are provided to ensure your safety:

fig_14.gif

Step 1 Ensure that you have at least three to four feet of working space at the rear of the chassis.

Step 2 Check the power supply bays and ensure that access is not blocked. If it is not, proceed to the following section "Inserting Power Supplies."

Step 3 If cables from other equipment fall in front of the power supply bay, carefully gather the cables (using care not to strain them) and use cable ties to anchor them away from the power supply bays. If no other equipment blocks access to the bay, proceed to the following section "Inserting Power Supplies."

Step 4 If access to the power supply bays is partially blocked by a power strip or other permanent rack fixture, you will need to detach the chassis from the rack and carefully slide it forward until you can maneuver each power supply into a bay. Make sure that at least one other person is available to support the front of the chassis as you push it out the front of the rack and, if necessary, to continue to support it while you insert the power supplies.

Step 5 Use a 3/16-inch flat-blade screwdriver to loosen the four screws that secure the left and right ears to the front mounting strips on the equipment rack.

fig_13.gif Caution Never attempt to lift or support the front of the chassis with the plastic front panels. The panels can break away and allow the chassis to drop.

Step 6 Position at least one person in front of the rack to support the front underside of the chassis and prevent it from falling as it is pushed forward out of the rack. Grasp the chassis along the metal undersides behind the plastic front panels. If possible, position two people in front of the rack, one person to support each side of the chassis.

Step 7 From the rear of the equipment rack, slowly push the chassis forward out of the rack until there is enough clearance for the power supplies to be inserted into the bay.

Step 8 If the chassis is installed near the bottom of the rack, allow the bottom front edge of the chassis to rest on the floor while you install the power supplies. If the chassis is too high in the rack for this to be practical, proceed to the following section "Inserting Power Supplies," and perform the steps as quickly as possible.

Step 9 When the power supplies are installed, push the chassis back into the rack until the ears meet the mounting strip on both sides of the equipment rack.

Step 10 Slide the chassis back into the rack until the ears meet the mounting strips on both sides of the rack.

Step 11 Secure each ear to the rack-mounting strip with two 10-32 x 3/8-inch slotted binder-head screws.

Step 12 Proceed to the section "Connecting AC and DC Power" later in this chapter.


Inserting Power Supplies

When you have clear access to the power supply bays, install the first AC-input or DC-input supply in the lower bay and the second supply, if any, in the upper bay. Each power supply weighs 20 pounds. Figure 3-2 shows the correct way to handle a power supply. Install each power supply as follows:

Step 1 Always install the first power supply in the lower bay. If a filler plate is installed on the lower bay, use a screwdriver to loosen the captive screw and remove the plate. Store the filler plate in a safe place; you should replace it whenever a power supply is not installed in the bay.

Step 2 Check the switch on the face of the power supply, and place it in the OFF (O) position. The interlock tab should not extend out of the unit.

Step 3 Hold the power supply by the handle and place your other hand underneath to support the bottom. (See Figure 3-2.)

Step 4 The power supply has casters on the bottom end. Place the casters inside the lower power supply slot and position the power supply so that it is aligned in the slot to go straight in.

Figure 3-2 Handling Power Supplies (AC-Input Power Supply Shown)

h1356.gif

fig_3.gif

Caution When inserting a power supply into the bay, do not use unnecessary force; slamming the power supply into the bay can damage the connectors on the rear of the supply and inside the chassis.

Step 5 Push the power supply all the way into the bay. Do not use unnecessary force; push the supply into the bay until the power supply front panel is flush with the chassis rear panel.

Step 6 Tighten the captive installation screw on the top of the power supply. This screw prevents the power supply from shifting away from the internal connector and provides proper grounding for the supply.

fig_4.gif Caution Do not turn on any power supplies until you are ready to power up the system. The interlock switch that locks the power supply in the slot also turns on the system power.

Step 7 If you are installing only one power supply, proceed to the following section "Connecting AC and DC Power."

Step 8 Use a number 2 Phillips or 1/4-inch flat-blade screwdriver to loosen the captive installation screw and remove the filler plate from the upper power supply bay. Save the filler plate so that you can replace it later if necessary.
Note Save the power supply filler plate. Install the filler plate over the upper power supply bay whenever the system is operating with one power supply.

Step 9 Repeat steps 2 through 6 for the second power supply.


Connecting AC and DC Power

For optimum reliability, connect redundant power supplies to separate input lines.

Note The installation must comply with all applicable codes and is approved for use with copper conductors only. The ground bond fastening hardware should be of compatible material and preclude loosening, deterioration, and electro-chemical corrosion of hardware and joined material. Attachment of the chassis ground to the central office or other interior ground system should be made with a Number 6 AWG copper ground conductor as a minimum. The Cisco 7507 chassis employs one threaded M4 x .7 chassis ground receptacle, which is intended to be bonded directly to the central offices or other interior ground system. This receptacle is located on the right side of the rear of the chassis. The chassis ground requires M4 x .7 bolts and locking hardware, which are not included.

Connect an AC-input power supply as follows:

Step 1 On the lower supply, push the cable-retention clip down, away from the power cord port, and plug in the power cord.

Step 2 To secure the cable in the power supply AC receptacle, push the cable-retention clip up until it snaps into place around the connector. The cable-retention clip provides strain relief for the AC power cord.

Step 3 Repeat Steps 1 and 2 for the second power supply, if any.

Step 4 Connect each power supply cord to a separate input line.

Step 5 To connect the external interface cables to the chassis, proceed to the following section "Connecting Interface Cables."

Connect a DC-input power supply as follows:

fig_16.gif

Warning When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor.

fig_2.gif Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.

Step 1 Using a flat-blade screwdriver, loosen the captive installation screws on the terminal block cover, then lift and remove the cover. (See Figure 3-3.)

Step 2 Wire the DC power supply using the appropriate lugs at the wiring end. The proper wiring sequence is ground to ground, positive to positive (line to L), and negative to negative (neutral to N). Note that the ground wire should always be connected first and disconnected last. (See Figure 3-3.)

The wire should be at least 8 AWG. Color code selection for the DC-input cable depends on the color code of the DC power source at your site. Typically, negative is black, positive is red or white, and ground is green. No matter which color code scheme is used, make certain it matches that used at the DC source for negative, positive, and ground. (See Figure 3-3.)

Figure 3-3 Installing the DC-Input Power Cable Leads, Nylon Cable Ties, and Cover

h2486.gif

fig_12.gif

Caution Incorrectly wiring the terminal block could damage the power supply, power source, and the Cisco 7507 chassis components.

Step 3 To provide strain relief for the three DC-input cable, attach two nylon ties around the cable and the metal bracket. (See Figure 3-3.)

Step 4 Install the terminal block cover over the terminal block, and tighten the captive installation screws. (See Figure 3-3.) Do not overtighten the captive installation screws on the terminal block cover. The recommended torque is 8.2 ±0.4 inch-lb.

Step 5 Connect the opposite end of the DC-input cable to the DC power source.

Warning After wiring the DC power supply, remove the tape from the circuit breaker switch handle and reinstate power by moving the handle of the circuit breaker to the ON position.

fig_10.gif

Step 6 Turn on the DC power source.
Note Do not turn on any power supplies until you are ready to power up the system. The interlock switch that locks the power supply in the slot also turns on the system power.

If you are installing or replacing a second power supply, repeat Step 1 through Step 5 for the second power supply. Proceed to the following section, to connect the external interface cables to the chassis.


Connecting Interface Cables

The following sections describe the basic network connections you will make to the router. Using the Configuration Worksheet will help you to make connections and later configure each interface without having to access the rear of the chassis to check port addresses. Complete the sample site log in Table 2-15, in the chapter "Preparing for Installation," if you have not already done so.


External Cabling Guidelines

The following guidelines will assist you in properly connecting the external network cables to your router.

Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode FDDI card when no cable is connected. Avoid exposure and do not stare into open apertures. Following is an example of the warning label that appears on the product:

fig_5.gif

h3567.gif

All FSIP serial ports are a high-density 60-pin receptacle. Each port requires a serial port adapter cable to connect to the external network. The cable determines both the electrical interface type and mode of the port to which it is connected. The network end of each adapter cable type is the industry-standard connector normally used for the interface type (for example, the EIA/TIA-232 port adapter cable has a standard DB-25 connector at the network end).

Following are guidelines for connecting serial interface cables:

Each port has a unique address composed of the interface processor slot number and the port number on the interface processor. For a description of interface addresses, refer to the section "Addresses and Port Numbers" in the chapter "Product Overview" and to the Port Configuration Worksheet in Figure 2-40.

Crossing high-power cables with interface cables can cause interference in some interface types. It will not always be possible to avoid this, but try to prevent it whenever possible.

Most interfaces provide some type of strain relief to prevent the cables from being accidentally disconnected. Among these types of strain relief are the slide fasteners on Ethernet cables, the cable retention clip on the power supply cord, and the screw-type fasteners on serial cables. Use all strain-relief devices provided to prevent potential problems caused by inadvertent cable disconnection.

Before applying power to the system, prevent unnecessary problems or component damage by double checking your cabling.

When setting up your system, you must consider a number of factors related to the cabling required for your connections. For example, when using EIA/TIA-232 connections, be aware of the distance and electromagnetic interference limitations. For cabling distances and other requirements, refer to the section "Site Requirements" in the chapter "Preparing for Installation."

Check the labels on the equipment and ensure that the power service at your site is suitable for the chassis you are connecting. If you are not sure, refer to power specifications in Table 1-1.
Note After installing all of the rear panel cables and powering up the system, you will proceed to the Router Products Getting Started Guide and Router Products Configuration Guide to configure and enable the interfaces.

If the router fails to operate in the manner specified in software documents, refer to the chapter "Troubleshooting the Installation" to help isolate the problem, and then notify a customer service representative. The sections that follow provide illustrations of the connections between the router interface ports and your network(s). Interface cables and equipment, such as Ethernet transceivers and interface cables, should already be available and in place. If they are not, refer to the section "Preparing Network Connections" in the chapter "Preparing for Installation" for descriptions of the equipment you need for each interface type to complete the connection to your network. Descriptions of network connections follow.


ATM Connections

All AIP ATM interfaces are full-duplex. You must use the appropriate ATM interface cable to connect the AIP with an external ATM network. The AIP provides an interface to ATM switching fabrics for transmitting and receiving data up to 155 megabits per second (Mbps) bidirectionally; the actual data rate is determined by the PLIM. The AIP can support interfaces that connect to the following physical layers:

Connect the AIP interface cables as shown in Figure 3-4. For detailed descriptions of ATM cabling requirements, refer to the section "Distance Limitations" in the chapter "Preparing for Installation" and the section "AIP Connection Equipment" in the chapter "Preparing for Installation."

Figure 3-4 ATM (AIP) Connections

h2638.gif

fig_7.gif

Caution To ensure compliance with EMI standards, the E3 PLIM connection requires an EMI filter clip (CLIP-E3-EMI) on the receive port (RCVR); the DS3 PLIM connection does not require this clip. Figure 3-5 shows the EMI filter clip assembly that is required for the E3 PLIM. Do not operate the E3 PLIM without this assembly.

The E3 and DS3 PLIMs require cable CAB-ATM-DS3/E3. If you have an E3 PLIM, you must follow Steps 1 through 3 to install the CAB-ATM-DS3/E3 cable and EMI filter assembly. If you do not have an E3 PLIM, proceed to the appropriate section for your configuration.

Step 1 Attach the CAB-ATM-DS3/E3 cable to the transmit (XMTR) and receive (RCVR) ports on the E3 PLIM. (See Figure 3-5a.)

One portion of the cable has a white insulator on both ends to ensure that the receive-to-transmit and transmit-to-receive relationship is maintained between the E3 PLIM and your ATM switch. The portion of the cable with the white insulator should attach between receive and transmit or transmit and receive ports of the E3 PLIM and your ATM switch, respectively.

Step 2 Hold the EMI filter clip as shown in Figure 3-5b and attach it to the receive cable as shown in Figure 3-5c.

Step 3 To ensure that the clip is not pulled off when adjacent interface processors are removed, position the clip parallel to the orientation of the AIP. (See Figure 3-5d.)

Figure 3-5 Installing the CAB-ATM-DS3/E3 Cable and EMI Filter Clip Assembly

Note Also refer to the Asynchronous Transfer Mode Interface Processor (AIP) Installation and Configuration configuration note (Document Number 78-1214-xx, where xx is the latest version of the document: -01, -02, and so forth), which is available on Cisco Connection Documentation CD-ROM or in print.


Channel Attachment Connections

Connecting bus and tag or Enterprise System Connection (ESCON) cables between the CIP and a host processor is beyond the scope of this publication. The specific CIP connection requirements are discussed in detail in the configuration note Channel Interface Processor (CIP) Installation and Configuration (Document Number 78-1342-xx). This configuration note ships with the CIP and is available on Cisco Connection Documentation CD-ROM.


Ethernet Connections

An Ethernet transceiver or MAU should already be connected to your network. Connect each Ethernet port on the EIP to an Ethernet transceiver with a transceiver cable, or to an attachment unit with an attachment unit interface (AUI). Figure 3-6 shows an example of a typical connection. Some transceivers connect directly to the Ethernet port on the EIP (usually the 10BASE-T type) and do not require an interface cable. On each EIP port, slide the metal bracket up over two posts on the cable connector, or tighten the thumbscrews to secure the cable in the port and provide strain relief. For descriptions of the connection equipment and connector locks, refer to the section "Ethernet Connection Equipment" in the chapter "Preparing for Installation."

Figure 3-6 Ethernet Connections

h1353.gif


Fast Ethernet Connections

For an MII connection, a 100BASE-T transceiver or MAU should already be connected to your network. The RJ-45 connection does not require an external transceiver.

On a single 100BASE-T port adapter, you can use either the RJ-45 connection or the MII connection. If you have two 100BASE-T port adapters on your FEIP, you can use the RJ-45 connection on one and the MII connection on the other.

Note Do not simultaneously connect MII and RJ-45 cables to one 100BASE-T port adapter. RJ-45 and MII cables are not available from Cisco Systems.

If you have RJ-45 connections, attach the Category 5 UTP cable directly to the RJ-45 port on the FEIP. (See Figure 3-7.)

If you have MII connections, attach an MII cable directly to the MII port on the FEIP or attach a 100BASE-T or 100BASE-F transceiver, with the media appropriate to your application, to the MII port on the FEIP. (See Figure 3-7.)

Attach the network end of your RJ-45 or MII cable to your 100BASE-T or 100BASE-F transceiver, switch, hub, repeater, DTE, or whatever external 100BASE-T equipment you have.

Figure 3-7 Fast Ethernet Connections

h3073.gif


Token Ring Connections

Media access unit (MAU) connectors provide a direct connection between the TRIP and the ring. Figure 3-8 shows the connections.

Figure 3-8 Token Ring Connections

h1383.gif


FDDI Connections

Both single-mode and multimode connections are available and can be combined on one FIP. The fiber-optic cable connects directly to the FIP ports. Single-mode uses separate transmit and receive cables. You will need two single-mode cables for a single attachment connection or four cables for a dual attachment connection. Multimode uses one integrated transmit/receive cable for each physical interface (one for PHY A and one for PHY B). You will need one multimode cable for a single attachment connection, and two cables for a dual attachment connection. Figure 3-14, which shows the connections for a dual attachment connection that uses both single-mode and multimode fiber, illustrates the types of connections used for both fiber modes. For pinout descriptions, refer to the section "FDDI Connection Equipment" in the chapter "Preparing for Installation."

Note Each station in a ring refers to its neighbor stations as upstream or downstream neighbors. The stream is based on the signal flow on the primary ring. A station receives the primary signal from its upstream neighbor and transmits the primary signal to its downstream neighbor.

This section also provides instructions for connecting an optical bypass switch to a dual attachment multimode network connection. Because the method of connecting optical bypass switches varies between different manufacturer's models, refer to the documentation for your particular bypass switch for correct connection instructions. If you are installing an optical bypass switch, proceed to the section "Installing an Optical Bypass Switch" later in this chapter.

Warning Invisible laser radiation may be emitted from the aperture ports of the single-mode FDDI card when no cable is connected. Avoid exposure and do not stare into open apertures. Following is an example of the warning label that appears on the product:

fig_6.gif

fig_8.gif


Single Attachment Connections

A FIP that is connected as a single attachment station (SAS) typically is connected to the ring through a concentrator. The FIP receives and transmits the signal through the same physical interface, usually PHY A. Depending upon whether you are connecting to a single-mode of multimode fiber network, connect the FIP as follows:

If you are connecting other FIPs as dual attachment stations (DASs), proceed to the following section. Otherwise, proceed to the section "Connecting the Console Terminal" later in this chapter.

Figure 3-9 Single Attachment Station (Single-Mode Fiber Network Connections)

h2628.gif

Figure 3-10 Single Attachment Station (Multimode Fiber Network Connections)

h2629.gif


Dual Attachment Connections

A FIP that is connected as a dual attachment station (DAS) connects to both the primary and secondary rings. The signal for each ring is received on one physical interface (PHY A or PHY B) and transmitted from the other. The standard connection scheme (which is shown in Figure 3-11) for a DAS dictates that the primary ring signal comes into the FIP on the PHY A receive port and returns to the primary ring from the PHY B transmit port. The secondary ring signal comes into the FIP on the PHY B receive port and returns to the secondary ring from the PHY A transmit port. Failure to observe this relationship will prevent the FDDI interface from initializing. Figure 3-14 shows the connections for a dual attachment that uses both multimode and single-mode fiber.

Figure 3-11 FDDI DAS Ports

h1550.gif

Depending upon whether you are connecting to a single-mode or multimode fiber network, connect the FIP as follows:

If you are connecting an optical bypass switch proceed to the next section. Otherwise, proceed to the section "Connecting the Console Terminal" later in this chapter.

Figure 3-14 FDDI Dual Attachment Network Connections (Single-Mode and Multimode)

h2632.gif


Installing an Optical Bypass Switch

An optical bypass switch is a device installed between the ring and the station that provides additional fault tolerance to the network. If a FIP that is connected to a bypass switch fails or shuts down, the bypass switch activates automatically and allows the light signal to pass directly through it, bypassing the FIP completely. A port for connecting an optical bypass switch is provided on the multimode/multimode FIP (CX-FIP-MM) and the single-mode/single-mode FIP (CX-FIP-SS) only. (See Figure 3-15 for CX-FIP-MM connections and Figure 3-16 for CX-FIP-SS connections.)

The optical bypass control port on the FIP is a six-pin mini-DIN receptacle. Some optical bypass switches use DIN connectors, and some use a mini-DIN. A DIN-to-mini-DIN control cable (CAB-FMDD) is included with the FIP to connect optical bypass switches that use the larger DIN connector. Up to 100 milliamperes of current can be supplied to the optical bypass switch.

Following are general instructions for connecting an optical bypass switch to the FIP; however, your particular bypass switch may require a different connection scheme. Use these steps as a general guideline, but refer to the instructions provided by the manufacturer of the switch for specific connection requirements.

Figure 3-15 FDDI Connection with Optical Bypass (CX-FIP-MM)

h1342.gif

Figure 3-16 FDDI Connection with Optical Bypass (CX-FIP-SS)

h2859.gif


Serial Connections

All FSIP ports support any available interface type and mode. The serial adapter cable determines the electrical interface type and mode of the port to which it is connected. EIA/TIA-232, EIA/TIA-449, V.35, and X.21 interfaces are available in DTE mode with a plug at the network end and in DCE mode with a receptacle at the network end. EIA-530 is available only in DTE mode with a plug. For descriptions and illustrations of each connector type, refer to the section "Serial Connection Equipment" in the chapter "Preparing for Installation." For cable pinouts, refer to the appendix "Cabling Specifications."

When connecting serial devices, consider the adapter cables as an extension of the router for external connections; therefore, use DTE cables to connect the router to remote DCE devices such as modems or data service units (DSUs), and use DCE cables to connect the router to remote DTE devices such as a host, PC, or another router. (See Figure 3-17.) The optional or additional connection equipment required depends on the interface type of each port.

A pair of metric thumbscrews is included with each port adapter cable. If you will connect to a remote device that uses metric hardware, replace the standard 4-40 thumbscrews at the network end of the port adapter cable with the M3 metric thumbscrews.

Figure 3-17 Serial Port Adapter Cable Connections

h1732.gif

Note The serial port adapter cable determines the electrical interface type and mode of the FSIP port. When connecting a remote DTE device (which means that the FSIP port is a DCE interface), you must set the clock rate with the clockrate command. For an example configuration using this command, refer to "Configuring Timing (Clock) Signals" in the chapter "Maintaining the Router." For complete command descriptions and instructions, refer to the related software documentation.


HSSI Connections

The HIP HSSI port functions as a DTE when it is connected to a DSU for a standard HSSI connection, and it can also be connected to a collocated router with a null modem cable. To connect the router to a HSSI network, use a HSSI interface cable between the HIP port and the DSU. Both ends of the HSSI interface cable are the same, so you can connect either end to the HIP or DSU. (See Figure 3-18.)

Figure 3-18 HSSI Network Connection

h1590.gif

To connect two routers back to back in order to verify the operation of the HSSI port or to build a larger node, use a null modem cable between available HSSI ports in two separate routers. (See Figure 3-19.) The two routers must be in the same location, and can be two Cisco 7507s, two Cisco 7505s, or one of each. When you configure the ports, you must enable the internal transmit clock on in the HSSI interface in both routers with command hssi internal-clock. To negate the command when you disconnect the cable, use the command no hssi internal-clock. For complete command descriptions and instructions, refer to the related software documentation.

Figure 3-19 HSSI Null Modem Connection (Two HIPs Connected Back to Back)

h2636.gif


MultiChannel Connections

Two standard T1 serial cables are available from Cisco Systems and other vendors for use with the MIP: null-modem and straight-through. These interface cables are used to connect your MIP to additional MIP s or external CSUs.

You must use null-modem cables for MIP-to-MIP connections and straight-through cables for MIP-to-CSU connections. The T1 cables used to connect the MIP with external T1 equipment have DB-15 male connectors on each end.

Four E1 cables are available from Cisco Systems and other vendors for use with the MIP: BNC, Twinax, DB-15, and RJ-45. The E1 cables used to connect the MIP with external equipment have a DB-15 male connector on the MIP end.

Connect the MIP cables as shown in Figure 3-20.

Figure 3-20 MIP Connections

h2637.gif


Connecting the Console Terminal

The system console port on the RSP2 is a DCE DB-25 receptacle for connecting a data terminal, which you will need to configure and communicate with your system. The port is located on the RSP2 below the auxiliary port and is labeled Console port as shown in Figure 3-21.

Note Both the console and auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)

Before connecting the console port, check your terminal's documentation to determine the baud rate of the terminal you will be using. The baud rate of the terminal must match the default baud rate (9600 baud). Set up the terminal as follows: 9600 baud, 8 data bits, no parity, and 2 stop bits

Use the console cable provided to connect the terminal to the console port on the RSP2, then follow the steps in the section "Starting the Router" later in this chapter.

Figure 3-21 Console and Auxiliary Port Connections

h3538.gif


Connecting Auxiliary Port Equipment

The auxiliary port is a DB-25 plug DTE port for connecting a modem or other DCE device (such as a CSU/DSU or other router) to the router. The port is located on the RSP2 above the console port and is labeled Auxiliary. An example of a modem connection is shown in Figure 3-21.

Note Both the console and auxiliary ports are asynchronous serial ports; any devices connected to these ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)


Using the Y Cables for Console and Auxiliary Connections

For systems with two RSP2s installed (one as master and one as slave in RSP2 slots 6 and 7), you can simultaneously connect console or auxiliary ports on both RSP2s using a special Y cable (CAB-RSP2CON= and CAB-RSP2AUX=). The master/slave switch on the RSP2 designates it as either the system master or slave. RSP2s ship as system masters by default. Figure 3-22 shows the console Y cable and Figure 3-23 shows the auxiliary Y cable.

Note Although the dual-RSP2 functionality is not available with the initial release of the RSP2 processor, console and auxiliary Y cables are shipped for future implementations.

Starting the Router

When all interfaces are connected, perform a final check of all connections, then power up the router as follows:

Step 1 Check the following components to make sure they are secure:

  • Each interface processor is inserted all the way into its slot, and all of the captive installation screws are tightened.

  • All interface cable connections are secured.

  • Any installed Flash memory cards are secure in their PCMCIA slots.

  • Each system power cable is connected and secured with the cable retention band or appropriate strain relief.

Step 2 Check the console terminal and make sure it is turned on.

Step 3 When you have checked all of the connection points above, turn on the power supply by turning the power switch clockwise to the ON position (|). The green, AC (or DC) OK and fan OK LEDs on each power supply should go on. After a few seconds, the red, out fail LED will turn OFF.

Step 4 Listen for the system blower; you should immediately hear it operating.

Step 5 On the RSP2, the normal LED indicator goes ON. If this indicator is not on after system initialization, an error occurred. Refer to the chapter "Troubleshooting the Installation" for troubleshooting procedures.

Step 6 During the boot process, the LED indicators on most of the interfaces go ON and OFF in irregular sequence. Some may go ON, go OFF, and go ON again for a short time. If an interface is already configured and brought on line, some LEDs will stay on during the entire boot process, such as the EIP receive LED, which stays on as it detects traffic on the line. Wait until the system boot is complete before attempting to verify the status of interface processor indicators.

Step 7 When the system boot is complete (a few seconds), the RSP2 begins to initialize the interface processors. During this initialization, the indicators on each interface processor behave differently (most flash ON and OFF). The enabled LED on each interface processor goes on when initialization has been completed, and the console screen displays a script and system banner similar to the following:

Compiled Wed 10-May-95 11:06

Step 8 When you start up the router for the first time, the system automatically enters the setup command facility, which determines which interfaces are installed and prompts you for configuration information for each one. On the console terminal, after the system displays the system banner and hardware configuration, you will see the following System Configuration Dialog prompt: 
         --- System Configuration Dialog ---        
At any point you may enter a questions mark `?' for help.
Refer to the `Getting Started' Guide for additional help.
Default settings are in square brackets `[]'. continue with
configuration dialog? [yes]:

You have the option of proceeding with the setup command facility to configure the interfaces, or exiting from setup and using configuration commands to configure global (system-wide) and interface-specific parameters. You do not have to configure the interfaces immediately; however, you cannot enable the interfaces or connect them to any networks until you have configured them.

Many of the interface processor LEDs will not go on until you have configured the interfaces. In order to verify correct operation of each interface, complete the first-time startup procedures and configuration, then refer to the LED descriptions in the appendix "Reading LED Indicators" to check the status of the interfaces.

Your installation is complete. Proceed to the appropriate software publications to configure your interfaces.

Note If the system does not complete each of these steps, proceed to the chapter "Troubleshooting the Installation" for troubleshooting recommendations and procedures.


Formatting a Flash Memory Card

The Flash memory card that shipped with your Cisco 7507 contains the Cisco IOS software image you need to boot your router. In some cases, you might need to insert a new Flash memory card and copy images or backup configuration files onto it. Before you can use a new Flash memory card, you must format it.

Note The following procedure assumes you have already booted your router.

fig_11.gif Caution The following formatting procedure erases all information on the Flash memory card. To prevent the loss of important data that might be stored on a Flash memory card, proceed carefully. If you wish to save the data on a Flash memory card, upload the data to a server before you format the card.

Use the following procedure to format a new Flash memory card:

Step 1 Using the procedure in the section "Installing and Removing a Flash Memory Card" in the chapter "Maintaining the Router," insert the Flash memory card into Slot 0. (If Slot 0 is not available, use Slot 1.)

Step 2 To format the Flash memory card, use the format slot0: (or format slot1:) command as follows. (Use only Intel Series 2+ Flash memory cards.) 
Router# format slot0:        
All sectors will be erased, proceed? [confirm]
Enter volume id (up to 30 characters): MyNewCard
Formatting sector 1
Format device slot0 completed
Router#
Note For this example, an 8-MB Flash memory card was used, and at the line "Formatting sector," the system counted the card's sectors backwards from 64 to 1 as it formatted them. For 16-MB Flash memory cards, the system counts backwards from 128 to 1, and for 20-MB Flash memory cards, the system counts backwards from 160 to 1.

The new Flash memory card is now formatted and ready to use.

Note For complete command descriptions and configuration information, refer to the Router Products Command Reference and the Router Products Configuration Guide.


Copying a Bootable Image into a Flash Memory Card

With the Flash memory card formatted, you can now copy a bootable image into it. To copy an image, use the following procedure, which assumes the following:

Note To assure access to a TFTP sever, you will need to configure at least one interface using the setup command facility. For instructions on using this procedure, refer to the Router Products Configuration Guide or Router Products Getting Started Guide publications.

Following is the procedure for copying a bootable file (called new.image) into the Flash memory card:

Step 1 Boot the router and allow it to initialize.

Step 2 Insert an unformatted Flash memory card and format it using the procedure in the section "Formatting a Flash Memory Card" in this chapter, and then proceed to Step 3.
Note If you have already formatted a Flash memory card, you can use it instead; however, you cannot boot from a Flash memory card formatted on another type of system. You must reformat it to use it as a boot source.

Step 3 To enable the router, copy the image new.image to the Flash memory card, make this image in the Flash memory card (in Slot 0) the default boot image, and reboot the router, use the following series of commands: 
Router> en        
Password:
Router# copy tftp:new.image slot0:new.image
20575008 bytes available on device slot0, proceed? [confirm]

Router#
Note In the previous example, the exclamation points (!!!) appear as the file is downloaded and the "C" characters signify calculation of the checksum, which is a verification that the file has been correctly downloaded to the Flash memory card. 
Router# config terminal        
Router(config)# no boot system
Router(config)# boot system flash slot0:new.image
Router(config)# ^z
Router# copy running-config startup-config
Router# reload

When the system reloads it will boot the image new.image from the Flash memory card in Slot 0.


Copying Bootable Images between Flash Memory Cards

As future releases of Cisco IOS images become available, you will receive these images as a file booted from a network server, a file on floppy disk, or a file on a Flash memory card.

The following scenario describes how to use a newly released image on a Flash memory card in a system that has an older image on a Flash memory card in Slot 0 and a default boot image in the onboard Flash SIMM.

For this scenario, the filenames are as follows:

You will copy the new image from the new Flash memory card onto the Flash memory card that contains the old image.

Note The scenario assumes that the new image will fit on the Flash memory card in Slot 0, alongside the old image. If there is not enough available space, use the delete command to delete files from the Flash memory card to make sufficient room for the new image; however, do not delete the image.old file. Then use the squeeze command to remove these deleted files from the Flash memory card. If, after you have deleted files and used the squeeze command, the two files cannot coexist on the Flash memory card in Slot 0, remove this card (place it in an antistatic bag and store it in a safe place), then insert the new Flash memory card (with the file image.new) in Slot 0. Proceed to Step 5 and use the command boot system flash slot0:image.new to designate the file image.new as the default boot image.

Step 1 Boot the router. By default, the file image.boot will be used.

Step 2 Enable the router as follows: 
Router> en        
Password:
Router#

Step 3 Insert the new Flash memory card in Slot 1.

Step 4 Use the following command to copy the file image.new in Slot 1 to the Flash memory card in Slot 0, only if there is enough memory space for the two images to coexist. If there is not enough memory space, proceed to Step 5. 
Router# copy slot1:image.new slot0:image.new
Note The previous command can also be entered as copy slot1:image.new slot0:.

Step 5 Use the following series of commands to designate the file image.new (which is in the Flash memory card in Slot 0) as the default boot image: 
Router# config t        
Router(config)# no boot system
Router(config)# boot system flash slot0:image.new
Router(config)# ^z
Router# copy running-config startup-config
Router# reload

When the system reloads, it will boot the file image.new from the Flash memory card in Slot 0.
