Warning Ultimate disposal of this product should be handled according to all national laws and regulations. For translated warnings, see "Product Disposal Warning".

Maintaining Safety with Electricity

Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or can weld the metal object to the terminals. For translated warnings, see "Jewelry Removal Warning".

Follow these guidelines when you work on equipment powered by electricity.

Locate the emergency power-OFF switch for the room in which you are working. Then, if an electrical accident occurs, you can act quickly to turn OFF the power.
Before working on the system, unplug the power cord.
Disconnect all power before doing the following:

Installing or removing a chassis
Working near power supplies

Warning When installing the unit, the ground connection must always be made first and disconnected last. For translated warnings, see "Ground Connection Warning".

Never assume that power is disconnected from a circuit. Always check.

Warning Read the installation instructions before you connect the system to its power source. For translated warnings, see "Installation Warning".

Look carefully for possible hazards in your work area, such as moist floors, ungrounded power extension cables, frayed power cords, and missing safety grounds.
If an electrical accident occurs, proceed as follows:

Use caution; do not become a victim yourself.
Turn OFF power to the system.
If possible, send another person to get medical aid. Otherwise, assess the condition of the victim and then call for help.
Determine if the person needs rescue breathing or external cardiac compressions; then take appropriate action.

Warning This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 15A U.S. (240 VAC, 10A international) is used on the phase conductors (all current-carrying conductors). For translated warnings, see "Circuit Breaker (15A) Warning".

Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. ESD damage occurs when electronic components are improperly handled and can result in complete or intermittent failures.

Always follow ESD-prevention procedures when you remove and replace components. Ensure that the chassis is electrically connected to earth ground. Wear an ESD-preventive wrist strap, ensuring that it makes good skin contact. Connect the grounding clip to an unpainted surface of the chassis frame to safely ground unwanted ESD voltages. To guard against ESD damage and shocks, the wrist strap and cord must operate properly. If no wrist strap is available, ground yourself by touching the metal part of the chassis.

Caution For safety, periodically check the resistance value of the antistatic strap, which should be between 1 and 10 megohm (Mohm).

Universal Router Module

The Universal Router Module (URM) delivers high-density voice interfaces, Fast Ethernet connectivity and ATM switching through a combination of Cisco IOS Release 12.1(5)YA and Switch Software (SWSW) Version 9.3.20 functionality.

The URM consists of a logically-partitioned front card connected to a universal router interface (URI) back card. The front card contains an embedded UXM-E running an Administration firmware image, and an embedded router (based on the Cisco 3660 router) running a Cisco IOS image. The embedded UXM-E and the embedded router connect through a logical internal ATM interface, with capability equivalent to an OC3 ATM port.

Note SWSW treats this interface as an OC3 ATM port, and this interface is the only port on the embedded UXM-E that is visible to SWSW.

Unlike the Cisco 3660 router, which has one slot for the motherboard and six slots for network modules, the embedded router has three virtual slots with built-in interfaces (see Table 4).

Table 4: Interfaces Found on Embedded Router Virtual Slots

Slot	Name	Description
Slot 0	ATM 0/0	The internal ATM interface connected to the embedded UXM-E ATM port.
Slot 1	FE1/0 and FE1/1	Fast Ethernet interfaces connected to the Fast Ethernet ports on the BC-URI-2FE2V back card.
Slot 2	T1 2/0 and T1 2/1; E1 2/0 and E1 2/1	T1 or E1 interfaces connected to the T1 or E1 ports on the VWIC installed in the back card.

Because the URM front card contains both an embedded UXM-E and an embedded Cisco router, the front card runs two separate software images with two different download procedures. For the embedded UXM-E, the Administration firmware image (Version XAA) is downloaded and saved to the embedded UXM-E Flash memory through SWSW command-line interface (CLI) commands, which are documented in Cisco IGX 8400 Series Installation and Configuration.

The embedded router runs Cisco IOS software. You can download and save the Cisco IOS image using standard Cisco IOS procedures as outlined in any documentation supporting
Cisco IOS Release 12.1(5)YA or later (see Cisco IOS Configuration Fundamentals Configuration Guide).

The embedded UXM-E hardware is based on the UXM-E card for the Cisco IGX series and features 16 MB asynchronous DRAM, 8 MB Flash memory, and 8 KB BRAM. The embedded router hardware is based on the Cisco 3660 modular-access router and features 8 MB boot Flash SIMM, 32 MB Cisco IOS Flash SIMM, and 128 KB NVRAM.

The back card (BC-URI-2FE2VT1 or BC-URI-2FE2VE1) contains an installed voice and WAN interface card (VWIC) with a generic dual-port T1 or E1 digital voice interface. See Figure 1 for a visual breakdown of the URM, and Table 5 for a hardware and software summary.

See Figure 3 to locate LEDs and interfaces on the URM back card. See Table 7 for a description of the physical ports on the back card, Table 8 for a description of the LEDs on the URI back card, and Table 9 for a description of the LEDs located on the installed VWIC.

Tip The VWIC-2MFT T1 or E1 must be installed in the appropriate BC-URI-2FE2V for the back card to function.

Different URIs are made by inserting the appropriate VWIC into the basic BC-URI-2FE2V back card. Two VWICs can be used: the VWIC-2MFT-T1 for T1 connections and the VWIC-2MFT-E1 for E1 connections.

The VWIC-2MFT is a generic dual port T1 (VWIC-2MFT-T1) or E1 (VWIC-2MFT-E1) digital voice interface in a combined voice and WAN interface card (VWIC) for voice applications. VWIC-2MFT provides the following services for T1 or E1 networks:

Trunk interface for voice services
TDM drop-and-insert services

At the physical layer, the VWIC provides two network interfaces through RJ-48C jacks with on-card TDM drop-and-insert capability, supported through router Cisco IOS reload operations. Because of the TDM backend, the VWIC is used as the front end for applications supporting channelized T1 and E1 services for voice.

Note For details on the VWIC T1 and E1 cards for voice connections, see the WAN Interface Cards Hardware Installation Guide.

URM Connections

The Cisco IGX backplane is a cell bus composed of four parallel data buses that transmit up to four cells at a time. This bus bandwidth is organized into allocated units called universal bandwidth units (UBUs), each capable of transmitting 4000 cells per second or 2000 fast packets per second. The Cisco IGX has a total of 584 UBUs, giving the Cisco IGX the capacity to transmit about 2 million cells or 1 million fast packets per second.

Each URM receives a default bandwidth from the Cisco IGX at power on. You can configure this default bandwidth by using the SWSW CLI command, cnfbusbw. For more information on this and other SWSW commands, refer to the Cisco WAN Switching Command Reference .

Note Except for slots 1 and 2 (which are reserved for the NPM), all slots in the Cisco IGX can be used to support a URM. However, the total number of UBUs allocated to all cards supported in the Cisco IGX cannot exceed the total Cisco IGX backplane bandwidth.

Connections terminating on the URM can be virtual path connections (VPC) or virtual channel connections (VCC).

The Cisco IOS router in the URM connects to Cisco IGX WAN through an internal ATM interface on the URM card. Because the URM supports voice connections using either standard VoIP or
Cisco proprietary VoATM configurations (using ATM PVCs on the internal ATM interface), the remote end of these connections is either an ATM PVC endpoint or a Frame Relay (FR) PVC endpoint.

Voice Connections on the URM

For voice applications, both the embedded UXM-E and the embedded router must be configured with WAN connections that terminate at the internal ATM port. The embedded router must also be configured with voice ports and dial-peers. The routing of a voice call from a voice port to the WAN connection depends on the destination information for each voice call (each call's routing information is described in the dial-peer configuration commands).

When a call is placed, the URM receives the call through one of the T1 or E1 ports on the URI back card, and decides where to route the call with the help of the embedded router dial-peers. ATM cells transfer from the embedded router to the Cisco IGX, then to the configured ATM PVC destination. At the destination, ATM cells travel from the Cisco IGX network into the embedded router of the destination URM. With the help of dial-peers, this destination router routes the cells to the appropriate voice port, which plays the voice into a T1/E1 channel.

Setting Up Communication in a Voice Network

When setting up a communication in a voice network using the URM, you will perform the following tasks (see "Configuring the URM" for details):

1. Use the SWSW CLI to set up connections between any Cisco IGX Frame Relay (FR) port or external ATM port and the internal ATM interface within the URM.

2. Use the Cisco IOS CLI to configure the corresponding ATM PVCs on the internal ATM interface.

3. Use the Cisco IOS CLI to program dial-peers that connect the VoIP or VoATM voice ports of the URM to the internal ATM interface.

Frame Relay Connections on the URM

Note Cisco IOS Release 12.1(5)YA does not support FRF.5/FRF.8 services for connections that originate or terminate in the embedded router.

FR connections that originate in the URM card cannot be configured to go over the internal ATM interface connecting the embedded router to the Cisco IGX WAN. Remote FR cards that support FRF.8 service interworking, such as the Cisco IGX UFM, should use FRF.8 service interwork at the FR/ATM network boundary to make end-to-end voice/data connections with the Cisco IGX URM.

The translational mode of the FRF.8 service interworking feature supports data and VoIP connections between the URM and remote FR endpoints. The transparent mode of FRF.8 service interworking allows the VoATM connections on URM to terminate in remote FR endpoints that have been configured for Voiceover Frame Relay (VoFR) operation.

End-to-end data and voice connections using VoIP are supported over both ATM trunks and fast packet trunks. See Table 14 for more information about voice and data connections supported on the URM.

URM Network Management

URM functionality is not supported by Cisco WAN Manager (CWM), CiscoWorks 2000 (CW2K) or Cisco Voice Manager (CVM); therefore, configuration information must be entered through SWSW CLI and Cisco IOS CLI. See the following network management features:

Initial Cisco IOS configuration on the URM requires you to access the Cisco IOS CLI through the hard-wired console port on the back card.
Initial Cisco IOS setup is configured through assignment of an IP address.
Each installed URM has its own IP address (which also serves as an external IP address).
IP-based protocols (Telnet, FTP, or TFTP) connect you to the Cisco IOS software; you can connect through either the internal ATM interface or the Fast Ethernet interfaces on the back card.
The URM reports its IP address to SWSW through ILMI topology discovery onboard the embedded UXM-E.
The embedded router is manageable through Cisco IOS CLI.
The embedded UXM-E is manageable through the SWSW CLI.

Note Information regarding card, interface, and connections in the Cisco IOS domain (such as number and status of the interfaces, call and connections status, and statistics) can be accessed through the Cisco IOS CLI only.

Installing the URM

You need the following tools and parts to install the URM:

ESD-preventive wrist strap
5/32-inch Allen wrench
Number 1 Phillips screwdriver

Tip To avoid bending any pins, install the back card first.

Installing the Back Card

Note The VWIC must be installed for the back card to function. Before installing the back card in the Cisco IGX chassis, verify that the correct VWIC is in place.

Step 1 Attach an ESD-preventive wrist strap before handling the card. The Cisco IGX 8400 series chassis has attached wrist straps on the front and the back of the chassis.

Caution Always follow ESD-prevention procedures when you remove and replace components. Wear an ESD-preventive wrist strap or ground yourself by periodically touching the metal part of the chassis.

Step 2 Visually inspect the BC-URI-2FE2V to verify that it is in good working order.

Step 3 Hold down the ejector levers and slide the back card into the chassis. Make sure that the ejector levers do not get caught behind the faceplate.

Step 4 Using the number 1 Phillips screwdriver, tighten the captive mounting screws on the top and bottom of the back card faceplate.

Installing the Front Card

Tip The front card must be connected to the back card for the URM to power on. If you install the front card before installing the back card, make sure that both cards are seated properly.

Step 1 Attach an ESD-preventive wrist strap before handling the card. The Cisco IGX 8400 series has attached wrist straps on the front and the back of the chassis.

Step 2 Using the 5/32-inch Allen wrench, open the Cisco IGX 8400 series switch door.

Step 3 Hold the card faceplate with one hand and support the card's weight with the other, then slide the card vertically into the selected slot. Hold down the ejector levers while seating the card (see Figure 4).

Caution Always use the ejector levers when disengaging or seating a card. Failure to do so can cause erroneous system error messages, and indicate module failure.

Note The URM automatically powers on when the card is seated. The front card faceplate LEDs will blink, indicating URM POST (see Figure 2 for LED location and description).

Step 4 Wait for the front card faceplate LEDs to finish cycling, then verify that the standby LED (STBY) is on.

Step 5 Using the number 1 Phillips screwdriver, tighten the panel fasteners at the top and bottom of the front card faceplate.

Step 6 Using the 5/32-inch Allen wrench, close the Cisco IGX 8400 series switch door.

Figure 4: Installing the URM Front Card in the Cisco IGX 8400 Series Chassis

Configuring the URM

During initial URM configuration, complete the following tasks:

1. Use SWSW commands to configure the internal ATM port.

2. Use SWSW commands to configure ATM connections onto the embedded UXM-E.

3. Use Cisco IOS commands to configure the internal ATM port for IP.

4. Use Cisco IOS commands to configure voice connections onto the embedded router.

For information on SWSW commands, refer to "WAN Switch Software for the URM", or to Cisco WAN Switching Command Reference .

For information on Cisco IOS commands, refer to "Cisco IOS Software for the URM", Cisco IOS Configuration Fundamentals Configuration Guide, Cisco IOS Release 12.1, or to any Cisco IOS documentation supporting Cisco IOS Release 12.1(5)YA (see "Obtaining Documentation" for more information).

TimeSaver To limit confusion between SWSW and Cisco IOS terminal sessions, complete the embedded UXM-E configuration using SWSW before configuring the embedded router using Cisco IOS software.

Step 1 Verify that the back and front cards are properly seated by checking the front card faceplate's active (ACT) LED (see Figure 2). If the LED is on, the cards are properly seated and the URM is powered on.

Step 2 Use the SWSW dspcds command to verify that the URM is in standby.

Step 3 (optional) Use the SWSW cnfrtr command to verify the following default configuration information:

The embedded router serial port is configured as CON.
The embedded router loads the Cisco IOS configuration from NPM, so will not enter the Cisco IOS setup utility.

TimeSaver Use cnfrtr slot n 1 to configure both parameters at the same time.

Note If you reconfigure the URM to load the Cisco IOS configuration from NVRAM, the router will enter the Cisco IOS setup utility.

Step 4 Use the SWSW addport command to create the internal ATM port. The addport slot.1 command activates the embedded UXM-E and powers on the embedded router.

When the embedded router powers on, the Cisco IOS image loads from the embedded router's boot Flash SIMM to the Flash SIMM. The factory-default Cisco IOS configuration loads from NPM.

Note By default, the URM's internal ATM interface is a UNI port with a maximum bandwidth of 353,208 calls per second (cps) (equivalent to an OC-3 ATM port); the interface cannot be configured as a NNI port.

Note If you have not connected a terminal to the CON port on the back card, you will not see the embedded router's initial start-up screens (see "Cisco IOS Software for the URM" for an example start-up screen).

Step 5 (optional) Use the SWSW cnfport command to configure the internal ATM port to support ILMI.

Note The port does not support LMI management protocol and should be configured to support either ILMI or none. If ILMI is not configured on the internal ATM port, the embedded UXM-E does not discover the assigned IP addresses for the URM card.

Step 6 Use the SWSW upport command to bring the internal ATM port to active state.

Step 7 Use the SWSW addcon command to configure ATM connections onto the embedded UXM-E. For more information on configuring ATM connections, see Cisco IGX 8400 Series Installation and Configuration.

TimeSaver If you want the Cisco IOS configuration to load from NVRAM in the future, use the SWSW cnfrtr slot r command at the SWSW CLI.

Step 8 Connect a dedicated console to the URM through the serial port (CON) located on the back card (see Figure 3).

Step 9 (optional) Use the Cisco IOS show version command to view information presented in the embedded router's initial start-up screens.

Step 10 (optional) To enter the Cisco IOS setup utility for basic configuration information, use the Cisco IOS setup command.

Step 11 Use the Cisco IOS command ip address in the interface configuration mode to configure an IP address onto the internal ATM interface.

TimeSaver Cisco IOS software does not automatically save configuration changes to the embedded router NVRAM. To avoid losing configuration changes, use the Cisco IOS copy run start command to save copies of your Cisco IOS running configuration to the embedded router NVRAM while you are working.

Step 12 Use an IP-based protocol (such as Telnet, FTP, or TFTP) to connect the management network with the embedded router. When connected, the embedded router reports assigned IP addresses to the embedded UXM-E through an ILMI topology discovery.

Tip Use the IP address configured on the internal ATM interface as the endpoint for a management VC between the URM and the management network.

Note For ILMI to discover and display the IP address, the internal ATM interface must have a configured IP address and ILMI must be configured on the internal ATM port. The ILMI protocol does not exchange any other IP addresses with the Cisco IGX.

Step 13 To configure ports on the URM, use Cisco IOS CLI commands. For more information, see Cisco IOS Configuration Fundamentals Configuration Guide.

Step 14 Configure voice connections on the URM using Cisco IOS CLI and SWSW CLI commands. For more information, refer to SWSW or Cisco IOS documentation listed in "Related Documentation".

The following differences between the two operating systems can impact connection setup:

SWSW CLI uses cells per second (cps) as the unit of measure for specifying traffic parameters; Cisco IOS software uses kilobytes per second (kbps).
SWSW and Cisco IOS software use different default values for traffic parameters.
URM system software and Cisco IOS software do not handle UBR connections in the same way.
Cisco IOS software limits the number of ABR connections to 100.

Cisco IGX allows a UNI specified range of 0 to 65535. However, the embedded router has a VCI range of 0 to 1023, so you cannot terminate connections with a VCI value greater than 1023 on the URM. The ATM PVCs configured onto the embedded router must correspond to the WAN connections configured onto the embedded UXM-E. If the two sides of a connection are inconsistent, try checking the traffic parameter values for each side to see if they are different, then redefine each value so that they are consistent.

Note The PVC with the address vpi.vci 0.1023 on the URM internal ATM port is reserved and is not available to the user.

Step 15 Save configuration changes to the embedded router NVRAM using the Cisco IOS copy run start command.

Step 16 If you have not already done so, reconfigure the embedded router to load the Cisco IOS configuration from NVRAM in the future using the SWSW cnfrtr slot r command at the SWSW CLI.

Tip After you have configured the embedded router, set up an external TFTP server to back up your Cisco IOS configuration. Use the Cisco IOS copy nvram tftp://host address/destination file command to copy the Cisco IOS configuration to the TFTP server.

If you have trouble, see "Obtaining Technical Assistance" on page 21 for information on how to get technical assistance.

WAN Switch Software for the URM

You can use standard and superuser commands on the SWSW CLI to create voice connections on the URM (see Table 10).

Note The Cisco IOS image stored in boot Flash is managed by SWSW; see "Managing the Boot Flash Cisco IOS Image" for more information.

Card management, port management, and connection management commands for the embedded UXM-E side of the URM are unchanged.

For details on command syntax and parameters, see Cisco WAN Switching Command Reference and Cisco WAN Switching SuperUser Command Reference . Note that the superuser commands are rarely used and many of them are only for debug purposes.

Note Because there is no physical line connecting the embedded UXM-E to the embedded Cisco IOS router, SWSW line connections and commands are not supported on the URM.

Managing the Boot Flash Cisco IOS Image

The URM boot Flash image is managed through SWSW commands entered at the SWSW CLI. By default, boot Flash memory is configured as read-only. However, the boot Flash memory can be reconfigured to read-write for Cisco IOS image updates using the following procedure.

Step 1 At the SWSW CLI, use the SWSW command cnfrtrparm slot 3 y. The terminal connected to the embedded router displays the following message:

%IPC_URM-6-BFLASH:Boot flash programmed Read/Write from IGX console

Step 2 Update the boot Flash Cisco IOS image using a standard Cisco IOS image update procedure (see Cisco IOS Configuration Fundamentals Configuration Guide for more information).

Step 3 At the SWSW CLI, use the SWSW command cnfrtrparm slot 3 n to reconfigure the boot Flash memory to read-only.

Cisco IOS Software for the URM

You can use standard Cisco IOS commands at the Cisco IOS CLI to configure voice connections on the URM. See Table 12 for a summary of Cisco IOS commands used to configure the URM for the first time.

The URM stores two Cisco IOS images: the main system image "urm-is-mz" stored in system Flash, and the boot helper image "urm-wboot-mz" stored in boot Flash. The boot Flash image is a Cisco IOS image with limited functionality and is used to recover from the loss or damage of the main Cisco IOS system image.

For information on how to recover from the loss or damage of the Cisco IOS system image, see Cisco IOS Configuration Fundamentals Configuration Guide.

For more information on Cisco IOS configuration and commands, see Cisco IOS Configuration Fundamentals Configuration Guide.

For details on command syntax and parameters, see Cisco IOS Configuration Fundamentals Command Reference.

To see a sample Cisco IOS start-up screen for the URM, see Example 8.

Cisco IOS Image Recovery

If the main Cisco IOS system image stored in Flash is lost or damaged, you can use the Cisco IOS boot helper image to copy backup images or configuration files from an external TFTP server or another online source.

Step 1 At the SWSW CLI, use the SWSW command cnfrtrparm slot 1 2 to configure the embedded router to load the boot helper image instead of the system image at router startup.

Step 2 Use the SWSW command resetcd or rstrtr to reboot the embedded router. The embedded router reboots using the Cisco IOS boot helper image.

Step 3 At the Cisco IOS CLI, repeat Steps 1 through 12 of the procedure described in "Configuring the URM".

Step 4 Using the Cisco IOS command copy, copy the saved Cisco IOS configuration file from the external TFTP server to the embedded router NVRAM.

Step 5 At the SWSW CLI, use the SWSW command cnfrtrparm slot 1 1 to configure the embedded router to load the system image at router startup.

Step 6 Use the SWSW command resetcd or rstrtr to reboot the embedded router. The embedded routerl reboots using the new Cisco IOS system image.

Replacing the URM

When replacing the URM, you should complete these tasks in the following order to avoid damage to the card:

1. Remove the front card.

2. Remove the back card.

3. Replace the back card.

4. Replace the front card.

5. Configure the card as appropriate.

Note The Cisco IOS software holds the embedded router in reset when the URI back card is removed; the embedded router does not resume until the URI back card is reseated.

Removing the Front and Back Cards

You need the following tools and parts to remove the front and back cards:

ESD-preventive wrist strap
5/32-inch Allen wrench
Number 1 Phillips screwdriver
Pencil or pen

Caution The VWIC component of the URI back card is not hot-swappable; removal of the VWIC can damage the URM.

Step 1 Using the Cisco IOS command copy, save the Cisco IOS configuration to an external TFTP server.

Step 2 In a separate terminal session, connect with the embedded UXM-E.

Step 3 Using the SWSW command cnfrtr slot n 1, reconfigure the embedded router to load the Cisco IOS configuration file from the NPM.

Step 4 Attach an ESD-preventive wrist strap before handling the card. The Cisco IGX 8410 cabinet has attached wrist straps on the front and the back of the chassis.

Step 5 Using the 5/32-inch Allen wrench, open the Cisco IGX 8400 series switch door.

Step 6 Using the number 1 Phillips screwdriver, loosen the panel fasteners at the top and bottom of the front card faceplate.

Step 7 Hold down the ejector levers while unseating the front card. Hold the card faceplate with one hand and support the card's weight with the other, then slide the card vertically out of the slot.

Caution Always use the ejector levers when disengaging or seating a card. Failure to do so can cause erroneous system error messages, and indicate module failure.

Step 8 Identify and mark any cable locations before removing cables from the back card, then unplug all cables.

Step 9 Using the number 1 Phillips screwdriver, loosen the captive mounting screws on the top and bottom of the back card faceplate.

Step 10 Hold down the ejector levels and slide the back card out of the cabinet.

Note The VWIC must be installed for the back card to function.

Replacing the Front and Back Cards

You need the following tools and parts to replace the front and back cards:

ESD-preventive wrist strap
5/32-inch Allen wrench
Number 1 Phillips screwdriver

Step 1 Attach an ESD-preventive wrist strap before handling the card. The Cisco IGX 8400 series cabinet has attached wrist straps on the front and the back of the chassis.

Step 2 Visually inspect the replacement BC-URI-2FE2V to verify it is in good working order.

Note The VWIC must be installed for the back card to function. Before installing the back card in the Cisco IGX chassis, verify that the correct VWIC is in place.

Step 3 Hold down the ejector levers and slide the back card into the cabinet. Make sure the ejector levers do not get caught behind the faceplate.

Caution Always use the ejector levers when disengaging or seating a card. Failure to do so can cause erroneous system error messages, and indicate module failure.

Step 4 Using the number 1 Phillips screwdriver, tighten the captive mounting screws on the top and bottom of the back card faceplate.

Step 5 Reconnect all cables according to the marks made before removing the card.

Step 6 Using the 5/32-inch Allen wrench, open the Cisco IGX 8400 series switch door.

Step 7 Hold the front card faceplate with one hand and support the card's weight with the other, then slide the card vertically into the selected slot. Hold down the ejector levers while seating the card.

Note The URM automatically powers on when the card is seated. The front card faceplate LEDs will blink, indicating URM POST (see Figure 2 for LED location and description).

Step 8 Wait for the front card faceplate LEDs to finish cycling, then verify that the standby LED (STBY) is on.

Step 9 Using the number 1 Phillips screwdriver, tighten the panel fasteners at the top and bottom of the front card faceplate.

Step 10 Using the 5/32-inch Allen wrench, close the Cisco IGX 8400 series switch door.

Step 11 Repeat Steps 1 through 12 of the procedure described in "Configuring the URM".

Step 12 Using the Cisco IOS command copy, copy the saved Cisco IOS configuration file from the external TFTP server to the embedded router NVRAM.
