Port Adapter Installation Prerequisites
This section provides software requirements, a list of parts and tools you will need to perform the port adapter installation, and safety and ESD-prevention guidelines to help you avoid injury and damage to the equipment during installation. Also included is information on the systems in which port adapters can be installed and overview information on interface specifications.
The following sections discuss general information and information about port adapter installation requirements:
Software and Hardware Requirements
The 4E port adapter requires that the host Cisco 7000 family router is running Cisco IOS Release 11.1(472) or later.
You need the following tools and parts to install a port adapter. If you need additional equipment, contact a service representative for ordering information.
Following are safety guidelines that you should follow when working with any equipment that connects to electrical power or telephone wiring.
Electrical Equipment Guidelines
Follow these basic guidelines when working with any electrical equipment:
Use the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:
Preventing Electrostatic Discharge Damage
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules comprise printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.
Following are guidelines for preventing ESD damage:
The term Ethernet is commonly used for all carrier sense multiple access/collision detection (CSMA/CD) local-area networks (LANs) that generally conform to Ethernet specifications, including IEEE 802.3. Ethernet Version 2 and IEEE 802.3 were based on, and developed shortly after, Ethernet Version 1. The slight differences between Ethernet and IEEE 802.3 are implemented in hardware, and both are supported automatically by the 4E without any hardware configuration changes. Together, Ethernet and IEEE 802.3 are the most widely used LAN protocols. They are well suited to applications where a local communication medium must carry sporadic, occasionally heavy traffic at high peak data rates.
Stations on a CSMA/CD LAN can access the network at any time. Before sending data, the station listens to the network to see of it is already in use. If it is, the station waits until the network is not in use, then transmits. A collision occurs when two stations listen for network traffic, hear none, and transmit simultaneously. When this happens, both transmissions are damaged, and the stations must retransmit. The stations detect the collision and use backoff algorithms to determine when they should retransmit.
Both Ethernet and IEEE 802.3 are broadcast networks, which means that all stations see all transmissions. Each station must examine received frames to determine whether it is the intended destination and, if it is, pass the frame to a higher protocol layer for processing. IEEE 802.3 specifies several different physical layers, and Ethernet defines only one.
Each IEEE 802.3 physical layer protocol has a name that summarizes its characteristics in the format speed/signaling method/segment length, where speed is the LAN speed in Mbps, signaling method is the signaling method used (either Baseband or Broadband), and segment length is the maximum length between stations in hundreds of meters.
IEEE 802.3 10BASE-T Specifications
Table 1 summarizes the characteristics of IEEE 802.3 Ethernet and Ethernet Version 2 for 10BASE-T.
Table 1 : IEEE 802.3 and 10BASE-T Ethernet Version 2 Physical Characteristics
Table 2 lists the cabling specifications for 10-Mbps transmission over UTP and STP cables.
Table 2 : Cable Specifications for 10-Mbps 10BASE-T
The 4E port adapter (PA-4E) provides up to four IEEE 802.3 Ethernet 10BASE-T interfaces. (See Figure 1.) Each Ethernet 10BASE-T interface allows a maximum bandwidth of 10-Mbps, for a maximum aggregate bandwidth of 40 Mbps. All four ports run at line (wire) speed.
Figure 1 : 4E Port Adapter, Faceplate View
The following additional sections discuss information specific to the 4E port adapter:
Port Adapter Locations on the VIP2 and in the Cisco 7200 Series Router
Figure 2 shows a VIP2 with installed port adapters. With the VIP2 oriented as shown in Figure 2, the left port adapter is in port adapter slot 0, and the right port adapter is in port adapter slot 1. Port adapters have handles that allow for easy installation and removal; however, they are occasionally not shown in this publication to highlight port adapter faceplate detail. In the Cisco 7000, Cisco 7507, and Cisco 7513 chassis the VIP2 is installed vertically. In the Cisco 7010 and Cisco 7505 chassis the VIP2 is installed horizontally.
Figure 2 : Two Port Adapters on the VIP2 (Horizontal Orientation Shown)
Figure 3 shows a Cisco 7206 with port adapters installed. In the Cisco 7206, port adapter slot 1 is in the lower left position and port adapter slot 6 is in the upper right position.
Figure 3 : Port Adapters in the Cisco 7206
The 4E port adapter contains the enabled LED, standard on all port adapters, and one status LED for each port, called the link LED. After system initialization, the enabled LED goes on to indicate that the 4E port adapter has been enabled for operation.When a 10BASE-T port is active, its link LED is on when a port on the 4E port adapter is receiving a carrier signal from the network. (The LEDs are shown in Figure 4.) The following conditions must be met before the enabled LED goes on:
If any of these conditions is not met, or if the initialization fails for other reasons, the enabled LED does not go on.
Figure 4 : LEDs on the 4E Port Adapter
4E Port Adapter Receptacles, Cables, and Pinouts
The interface connectors on the 4E port adapter are four individual RJ-45 receptacles. You can use all four simultaneously. Each connection supports IEEE 802.3 and Ethernet 10BASE-T interfaces compliant with appropriate standards. The RJ-45 connections require external transceivers. Cisco Systems does not supply Category 5 UTP RJ-45 cables; these cables are available commercially.
Figure 5 shows the RJ-45 connectors. Table 3 lists the pinouts and signals for the RJ-45 connectors.
Figure 5 : 4E RJ-45 Connections, Plug and Receptacle
Table 3 : 4E RJ-45 Connector Pinout
Depending on your 4E, RJ-45 interface cabling requirements, use the pinouts in Figure 6 and Figure 7.
Figure 6 : Straight-Through Cable Pinout, 4E RJ-45 Connection to a Hub or Repeater
Figure 7 : Crossover Cable Pinout, 4E RJ-45 Connections Between Hubs and Repeaters
The 4E port adapter is used on the VIP2, and can be installed in either port adapter slot 0 or port adapter slot 1. Figure 8 shows a 4E port adapter installed on a VIP2 in port adapter slot 0.
Figure 8 : VIP2 with a 4E Port Adapter in Port Adapter Slot 0
The following sections include information specific to the 4E port adapter and its use on the VIP2 in Cisco 7000 family routers:
Installing or Replacing a Port Adapter on a VIP2
Depending on the circumstances you might need to install a new port adapter on a VIP2 motherboard or replace a failed port adapter in the field. In either case, you need a number 1 Phillips screwdriver, an antistatic mat onto which you can place the removed interface processor, and an antistatic container into which you can place a failed port adapter for shipment back to the factory.
When only one port adapter is installed on a VIP2, a blank port adapter must fill the empty slot to allow the VIP2 and router chassis to conform to electromagnetic interference (EMI) emissions requirements, and so that air flows through the chassis properly. If you plan to install a new port adapter, you must first remove the blank port adapter.
Following is the standard procedure for removing and replacing any type of port adapter on the VIP2:
Figure 9 : Location of Port Adapter Screw, Partial Port Adapter View
Figure 10 : Pulling a Port Adapter Out of a Slot, Partial Port Adapter View
Figure 11 : Removing a Port Adapter
Figure 12 : Aligning the Carrier Edge with Upper and Lower Slot Edges, Partial View
This completes the procedure for installing a new port adapter or replacing a port adapter on a VIP2.
Attaching 4E Port Adapter Interface Cables
On a single 4E port adapter, you can use up to four RJ-45 connections. RJ-45 cables are not available from Cisco Systems; they are available from outside commercial cable vendors.
Connect RJ-45 cables to the 4E port adapter as follows:
Figure 13 : Connecting 4E RJ-45 Cables (Horizontal Orientation---Shown without Handles)
This completes the 4E port adapter installation.
If you installed a new 4E port adapter or if you want to change the configuration of an existing interface, you must enter Configuration mode using the configure command. If you replaced a 4E port adapter that was previously configured, the system will recognize the new 4E interfaces and bring them up in their existing configuration.
After you verify that the new 4E port adapter is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Be prepared with the information you will need, such as the following:
For a summary of the configuration options available and instructions for configuring the 4E interfaces on the VIP2, refer to the appropriate configuration publications listed in the section "If You Need More Information" on page 2.
The configure command requires privileged-level access to the EXEC command interpreter, which usually requires a password. Contact your system administrator if necessary to obtain EXEC-level access.
Selecting Chassis Slot, Port Adapter, and Ethernet 10BASE-T Interface Port Numbers
The following section describes how to identify chassis slot, port adapter, and Ethernet 10BASE-T interface port numbers.
In the router, physical port addresses specify the actual physical location of each interface port on the router interface processor end. (See Figure 14.) This address is composed of a three-part number in the format chassis slot number/port adapter number/interface port number, as follows:
Interface ports on the VIP2 maintain the same address regardless of whether other interface processors are installed or removed. However, when you move a VIP2 to a different slot, the first number in the address changes to reflect the new chassis slot number.
Figure 14 shows the port adapter slots and interface ports of a sample Cisco 7505 system. On the VIP2, the first port adapter slot number is always 0. The second port adapter slot number is always 1. The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter.
For example, the four 10BASE-T interface ports on a 4E port adapter in the first port adapter slot in chassis slot 3, would have the following addresses: 3/0/0, 3/0/1, 3/0/2, and 3/0/3. (See Figure 14.) If the 4E port adapter was in port adapter slot 1, these same interface ports would be numbered 3/1/0 through 3/1/3. Port adapters can occupy either port adapter slot. There are no restrictions.
Figure 14 : 10BASE-T Interface Port Number Example (Cisco 7505 Shown)
You can identify interface ports by physically checking the slot/port adapter/interface port location on the back of the router or by using show commands to display information about a specific interface or all interfaces in the router.
The following steps describe a basic configuration. Press the Return key after each step unless otherwise noted. At any time you can exit the privileged level and return to the user level by entering disable at the prompt as follows:
Following is an example of a basic configuration procedure:
To check the interface configuration using show commands, proceed to the section "Checking the Configuration."
After configuring the new interface, use the show commands to display the status of the new interface or all interfaces and the ping command to check connectivity.
Using show Commands to Verify the VIP2 Status
The following steps use show commands to verify that the new interfaces are configured and operating correctly.
If the interface is down and you configured it as up, or if the displays indicate that the hardware is not functioning properly, ensure that the network interface is properly connected and terminated. If you still have problems bringing the interface up, contact a service representative for assistance.
Using show Commands to Display Interface Information To display information about a specific interface, use the show interfaces command with the interface type and port address in the format show interfaces [type slot/port adapter/port].
Following is an example of how the show interfaces [type slot/port adapter/port] command displays status information (including the physical slot and port address) for the interfaces you specify. In these examples, most of the status information for each interface is omitted, and the four Ethernet 10BASE-T interfaces (0--3) are in chassis slot 3, in port adapter slot 0. (Interfaces are administratively shut down until you enable them.)
With the show interfaces type slot/port adapter/port command, use arguments such as the interface type (ethernet, and so forth) and the slot, port adapter, and port numbers (slot/port adapter/port) to display information about a specific Ethernet 10BASE-T interface only.
The following example of the show interfaces ethernet slot/port adapter/port command shows all of the information specific to the first 4E interface port (interface port 0) in chassis slot 3, port adapter slot 1:
The show version (or show hardware) command displays the configuration of the system hardware (the number of each interface processor type installed), the software version, the names and sources of configuration files, and the boot images. Following is an example of the show version command used with a Cisco 7500 series system:
To determine which type of port adapter is installed on a VIP2 in your system, use the show diag slot command. Specific port adapter information is displayed, as shown in the following example of an 4E port adapter in chassis slot 11:
Using the ping Command The packet internet groper (ping) command allows you to verify that an interface port is functioning properly and to check the path between a specific port and connected devices at various locations on the network. This section provides brief descriptions of the ping command. After you verify that the system and VIP2 have booted successfully and are operational, you can use this command to verify the status of interface ports. Refer to the publications listed in the section "If You Need More Information" on page 2, for detailed command descriptions and examples.
The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal that is not returned before the specified time-out is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed] indicate that the connection failed.
Following is an example of a successful ping command to a remote server with the address 1.1.1.10:
Cisco 7200 Series and the 4E Port Adapter
The 4E port adapter is used in the Cisco 7200 series routers and can be installed in any of the available port adapter slots. Figure 15 shows a 4E port adapter installed in port adapter slot 3 of a Cisco 7206.
Figure 15 : Cisco 7206 with a 4E Port Adapter in Port Adapter Slot 3
The following sections include information that is specific to the 4E port adapter and its use in the Cisco 7200 series routers:
Installing or Replacing a Port Adapter in Cisco 7200 Series Routers
Depending on your circumstances, you might need to install a new port adapter in a Cisco 7200 series router or replace a failed port adapter in the field. In either case, no tools are necessary; all port adapters available for the Cisco 7200 series connect directly to the router midplane and are locked into position by a port adapter lever. When removing and replacing a port adapter, you will need an antistatic mat onto which you can place a removed port adapter and an antistatic container into which you can place a failed port adapter for shipment back to the factory.
When a port adapter slot is not in use, a blank port adapter must fill the empty slot to allow the router to conform to EMI emissions requirements and to allow proper air flow across the port adapters. If you plan to install a new port adapter in a slot that is not in use, you must first remove a blank port adapter.
Following is the procedure for removing a port adapter from a Cisco 7200 series router:
Figure 16 : Placing the Port Adapter Lever in the Unlocked Position (Cisco 7206 shown)
Figure 17 : Handling a Port Adapter
This completes the procedure for removing a port adapter from a Cisco 7200 series router.
Following is the procedure for installing a new port adapter in a Cisco 7200 series router:
Figure 18 : Aligning the Port Adapter Metal Carrier Between the Slot Guides (Cisco 7206 shown)
Figure 19 : Placing the Port Adapter Lever in the Locked Position (Cisco 7206 shown)
This completes the procedure for installing a new port adapter in a Cisco 7200 series router.
Attaching 4E Port Adapter Interface Cables
On a single 4E port adapter, you can use up to four RJ-45 connections. RJ-45 cables are not available from Cisco Systems; they are available from outside commercial cable vendors.
Connect RJ-45 cables to the 4E port adapter as follows:
Figure 20 : Connecting 4E RJ-45 Cables
This completes the procedure for attaching 4E port adapter interface cables.
If you installed a new 4E port adapter or if you want to change the configuration of an existing interface, you must enter Configuration mode using the configure command. If you replaced a 4E port adapter that was previously configured, the system will recognize the new 4E interfaces and bring them up in their existing configuration.
After you verify that the new 4E port adapter is installed correctly (the enabled LED goes on), use the privileged-level configure command to configure the new interfaces. Be prepared with the information you will need, such as the following:

Selecting Port Adapter Slot and Ethernet 10BASE-T Interface Port Numbers
The following section describes how to identify port adapter slot and Ethernet 10BASE-T interface port numbers.
Physical port addresses specify the actual physical location of each interface port on the router. (See Figure 21.) This address is composed of a two-part number in the format port adapter slot number/interface port number, as follows:
Interface ports maintain the same address regardless of whether other port adapters are installed or removed from the slot. However, when you move a port adapter to a different slot, the first number in the address changes to reflect the new chassis slot number.
Figure 21 shows the port adapter slots and interface ports of a Cisco 7206. The port adapter slot numbers start with 1 and continue through 6 (slot 0 is always reserved for the Fast Ethernet port on the I/O controller---if present). The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter.
For example, the four 10BASE-T interface ports on a 4E port adapter in port adapter slot 3 would have the following addresses: 3/0, 3/1, 3/2, and 3/3. (See Figure 21.) If the 4E port adapter was in port adapter slot 1, these same interface ports would be numbered 1/0 through 1/3. Port adapters can occupy any port adapter slot. There are no restrictions.

SELV Circuit Warning Translations
Warning The ports labeled "Ethernet," "10BASE-T," "Token Ring," "Console," and "AUX" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the BRI circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits.
Waarschuwing De poorten die "Ethernet", "10BASE-T", "Token Ring", "Console" en "AUX" zijn gelabeld, zijn veiligheidscircuits met extra lage spanning (genaamd SELV = Safety Extra-Low Voltage). SELV-circuits mogen alleen met andere SELV-circuits verbonden worden. Omdat de BRI-circuits op dezelfde manier als telefoonnetwerkspanning behandeld worden, mag u het SELV-circuit niet verbinden met de telefoonnetwerkspanning (TNV) circuits.
Varoitus Portit, joissa on nimet "Ethernet", "10BASE-T", "Token Ring", "Console" ja "AUX", ovat erityisen pienen jännityksen omaavia turvallisuuspiirejä (SELV-piirejä). Tällaiset SELV-piirit tulee yhdistää ainoastaan muihin SELV-piireihin. Koska perusluokan liitäntöjen (Basic Rate Interface- eli BRI-liitännät) jännite vastaa puhelinverkoston jännitettä, vältä SELV-piirin yhdistämistä puhelinverkoston jännitepiireihin (TNV-piireihin).
Attention Les ports étiquetés « Ethernet », « 10BASE-T », « Token Ring », « Console » et « AUX » sont des circuits de sécurité basse tension (Safety Extra-Low Voltage ou SELV). Les circuits SELV ne doivent être interconnectés qu'avec d'autres circuits SELV. Comme les circuits BRI sont considérés comme des sources de tension de réseau téléphonique, éviter de connecter un circuit SELV à un circuit de tension de réseau téléphonique (telephone network voltage ou TNV).
Warnung Die mit "Ethernet", "10BASE-T", "Token Ring", "Console" und "AUX" beschrifteten Buchsen sind Sicherheitskreise mit Sicherheitskleinspannung (Safety Extra-Low Voltage, SELV). SELV-Kreise sollten ausschließlich an andere SELV-Kreise angeschlossen werden. Da die BRI-Kreise wie Telefonnetzspannungen behandelt werden, ist der SELV-Kreis nicht an Telefonnetzspannungskreise (TNV) anzuschließen.
Avvertenza Le porte contrassegnate da "Ethernet", "10BASE-T", "TokenRing", "Console" e "AUX" sono circuiti di sicurezza con tensione molto bassa (SELV). I circuiti SELV devono essere collegati solo ad altri circuiti SELV. Dato che i circuiti BRI vengono trattati come tensioni di rete telefonica, evitare di collegare il circuito SELV ai circuiti in cui è presente le tensione di rete telefonica (TNV).
Advarsel Utgangene merket "Ethernet", "10BASE-T", "Token Ring", "Console" og "AUX" er lavspentkretser (SELV) for ekstra sikkerhet. SELV-kretser skal kun kobles til andre SELV-kretser. Fordi BRI-kretsene håndteres som telenettspenning, unngå å koble SELV-kretsen til kretser for telenettspenning (TNV).
Aviso As portas "Ethernet", "10BASE-T", "Token Ring", "Console", and "AUX" são circuitos de segurança de baixa tensão (SELV). Estes circuitos deverão ser apenas ligados a outros circuitos SELV. Devido ao facto de os circuitos BRI (Interface de Ritmo Básico) serem tratados como sendo de tensão equivalente à da rede telefónica, evite ligar o circuito SELV aos circuitos TNV (tensão de rede telefónica).
¡Advertencia! Los puertos "Ethernet", "10BASE-T", "Token Ring", "Console" y "AUX" son circuitos de muy baja señal que garantizan ausencia de peligro (Safety Extra-Low Voltage = SELV). Estos circuitos SELV deben ser conectados exclusivamente con otros también de tipo SELV. Puesto que los circuitos tipo BRI se comportan como aquéllos con voltajes de red telefónica, debe evitarse conectar circuitos SELV con circuitos de voltaje de red telefónica (TNV).
Varning! De portar som är märkta "Ethernet", "10BASE-T", "Token Ring", "Console" och "AUX" är SELV-kretsar, d.v.s. skyddskretsar med extra låg spänning (SELV: Safety Extra-Low Voltage = skyddsklenspänning). SELV-kretsar får endast anslutas till andra SELV-kretsar. Eftersom BRI-kretsar behandlas liksom telefonnätsspänning bör SELV-kretsen inte anslutas till telefonnätsspänningskretsar (TNV-kretsar).
