Installing the Router

This chapter guides you through the installation of the router and includes the following sections:

Caution If you plan to place the router on a desk or table, do not place anything on top of the router that weighs in excess of 10 pounds (4.5 kg). Excessive weight on top could damage the chassis.


Required Tools and Parts

Following are the tools and parts required to install the router:

In addition, you might need the following external equipment:


Installing the Rubber Feet

This section explains how to install the rubber feet on the bottom of the chassis. If you want to rack-mount the chassis, skip this section and proceed with the next section, "Rack-Mounting the Chassis." If you want to wall-mount the chassis, skip this section and proceed with the section "Wall-Mounting the Chassis" later in this chapter.

Before placing the router on a desktop, shelf, or other flat, secure surface, perform the following steps to install the rubber feet:

Step 1 Locate the rubber feet on the black adhesive strip that shipped with the chassis. (See Figure 3-1.)

Note If you are installing a model 2501, 2503, 2509, 2511, 2513, or 2514 and your Ethernet connection requires jackscrews, remove the slide-latch assembly from the AUI connector and attach the jackscrews provided.


Connecting the DC-Input Power Supply

This section describes the Cisco 2500 series direct current (DC) power supply specifications and wiring. This procedure covers the following information:


DC Power Specifications

The Cisco 2500 DC-input power supply is intended for use in DC operating environments. Table 3-1 lists the power supply specifications.

Table 3-1 : Cisco 2500 DC-Input Power Supply Specifications

Description Design Specification
Power 40W, -40 to -72 VDC
Wire gauge for power connections 14 AWG1

1 AWG=American Wire Gauge.


Wiring the DC-Input Power Supply

If you ordered a Cisco 2500 series router with a DC-input power supply, follow the directions in this section for proper wiring. Figure 3-18 shows the rear of the DC-input power supply (Model 2501-DC).

fig_8.gif Warning Before conducting 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.

Note The installation must comply with all applicable codes.

Note This product is intended for installation in restricted access areas and is approved for use with copper conductors only.

Figure 3-18 : Cisco 2500 Series DC-Input Power Supply---Rear View

h2857.gif

Figure 3-19 shows the DC-input power supply terminal block. Follow these procedures for wiring the terminal block:

Step 1 Attach the appropriate lugs at the wire end of the power supply cord.

Step 2 Wire the DC-input power supply to the terminal block as shown in Figure 3-19. The proper wiring sequence is ground to ground, positive to positive, and negative to negative.

fig_9.gif Caution Do not overtorque the terminal block captive thumbscrew or terminal block contact screws. The recommended torque is 8.2 ± 0.4 inch-lb.

fig_10.gif Caution Secure the wires so that they will not be disturbed by casual contact. For example, secure the wires to a rack frame using tie wraps.

Step 3 Remove the tape from the circuit breaker switch handle and restore power by moving the circuit breaker handle to the ON position.

Connecting to the Network

If your router has an Ethernet port, follow Step 1. If it has a Token Ring port, proceed to Step 3. If your router has both an Ethernet and Token Ring port (model 2515), start with Step 1.

Step 1 Connect the Ethernet port to the transceiver as shown in Figure 3-20.

Figure 3-20 : Ethernet Transition Cable Connections

h2046.gif

Step 2 If necessary, extend the Ethernet cable as shown in Figure 3-21, otherwise, proceed to
Step 4.

Figure 3-21 : Extending the Transition Cable from the Ethernet Port

h2047.gif

Step 3 Connect the Token Ring port to the MAU as shown in Figure 3-22.

Figure 3-22 : Token Ring Cable Connections

h1904.gif

Step 4 Connect the serial ports to the modem or CSU/DSU as shown in Figure 3-23. Make certain to connect the 60-pin serial port connector as shown.

Figure 3-23 : Serial Cable Connections

h2015.gif

Step 5 On hub models, connect RJ-45 cables from the Ethernet ports to transceivers. If you have a router model go to Step 9, and if you have a access server, omit this step and continue with Step 6.

Step 6 On access server models, connect a SCSI-type breakout cable (available from Cisco Systems) to each 68-pin port. If you have a 68-pin-to-RJ-45 breakout cable, use RJ-45-to-DB-25 adapters to connect the breakout cable to your serial devices. Or, if you have a 68-pin-to-DB-25 breakout cable, connect the DB-25 connector directly to your serial devices. Refer to the appendix "Cabling Specifications" for more information. Continue with Step 9.

fig_3.gif Caution Make sure that the SCSI connector on the breakout cable is securely connected to the SCSI connector on the access server. A short could occur which might damage your access server if the connection is disconnected.

Step 7 The Basic Rate Interface (BRI) port, a female RJ-45 connector on models 2503 and 2504 (see Figure 3-24), is located on the chassis rear panel between the serial 1 and console ports. On the Cisco 2516, the BRI port is located between the serial and Ethernet ports.

On the Cisco 2516, set the MDI/MDI-X switch to MDI-X to configure the hub as a standalone hub. Set the MDI/MDI-X switch to MDI to configure Ethernet port 6 on the hub for connecting to another hub.

Step 8 Using the appropriate cable, connect the BRI port to the Integrated Services Digital Network (ISDN) through the NT1. The common carrier will provide the NT1 connection worldwide, except in North America, where the NT1 is customer provided.

Figure 3-24 : BRI Interface Port---RJ-45 Female Connector

h1906.gif

fig_4.gif Warning Network hazardous voltages are accessible in the BRI cable. If you detach the BRI cable, detach the end away from the router first to avoid possible electric shock. Network hazardous voltages also are accessible on the system card in the area of the BRI port (RJ-45 connector), regardless of when power is turned off. (See Figure 3-25.)

Figure 3-25 : Network Hazardous Voltage Area near the BRI Port

h1963.gif

Step 9 Connect the console and auxiliary ports as required for your method of configuration or if future configuration is desired. Depending on your terminal or modem connections, the console and auxiliary ports may require an RJ-45-to-DB-25 or RJ-45-to-DB-9 adapter (labelled "Terminal"). Your terminal or terminal emulation software should be configured for 9600 baud, 8 data bits, no parity, and 2 stop bits.

fig_7.gif Caution To prevent damage to the system, make certain you connect the BRI cable to the BRI connector only and not to any other RJ-45 connector. The console, auxiliary, and BRI ports all use RJ-45 connectors.

Step 10 Using an M 3.5 thread-forming screw (not included), attach a ground wire to the protective grounding terminal on the chassis rear panel as required by your installation.
(See Figure 3-14.)

Step 11 Connect the power cable between the router and the AC source.


What to Do after Installing the Router Hardware

After you install the router hardware, the system is ready to be powered on and configured. For information on router software configuration, refer to the appropriate software publications. If you are installing the router in the European Community, Italy, or the United Kingdom, refer to the Cisco 2500 Public Network Certification publication that accompanied the chassis for information about connection requirements and related safety warnings.
