1 Description

The Cisco Performance Routing Engine (ESR-PRE2) is a single-slot module that performs Layer 2 and Layer 3 packet routing and forwarding using Parallel eXpress Forwarding (PXF).

2 Upgrading to a PRE2

This upgrade should be performed by a qualified engineer who is familiar with the Cisco router console interface.

Upgrade Considerations

• This is a service-impacting hardware upgrade.

The router will not be available for user traffic during the upgrade, and traffic cannot resume until the upgrade is complete.

• PREs or PRE1s cannot operate with a PRE2 in the same chassis and should never be installed in a chassis together.

• PRE2 modules to be installed must have the helper image (eboot) stored in the onboard boot flash, no configuration, and must be set to boot into ROMMON. Individual PRE2 modules ship in this state.

• The new PRE2 image must exist on the TFTP server.

Saving the Startup and Running Configuration Information

When the PRE or PRE1 is removed from the chassis, any local configuration is lost. You must save your configuration information to the TFTP server or media card before removing the module.

If you plan to use the media card from your current PRE or PRE1, you can save your startup configuration, running configuration, and the latest PRE2 image (from the TFTP server) to the media card.

Saving to a Media Card

Step 1 Connect the console to the primary PRE or

PRE1.

Step 2 Copy the startup configuration and

running configuration to the existing removable media card.

Step 3 Download the full PRE2 image from the

TFTP server to the media card.

Step 4 If you have a redundant PRE or PRE1,

save this information on the redundant PRE or PRE1 media card.

Step 5 Remove the media cards from the modules

and set them aside.

Saving to the TFTP Server

Step 1 Connect to the primary PRE or PRE1

console.

Step 2 Save the startup configuration and

running configuration to the TFTP server.

Removing the PRE or PRE1 Module

Note Modules can be hot-swapped. However,

removing a module terminates all traffic. We recommend that you power down th e router to ensure a successful installation.

Warning

Step 1 Ensure that you are properly grounded. Step 2 Power down the router Step 3 Disconnect the cables from the PRE/PRE1.

Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing.

Statement 1034

Step 4 Unscrew the captive screws. Step 5 Simultaneously pivot both ejector levers

away from each other to disengage the module from the backplane.

Step 6 Slide the PRE/PRE1 out of the slot and

place it on an anti-static surface or in an anti-static bag.

Step 7 If you are replacing a redundant

PRE/PRE1, repeat Step 3 through Step 6.

Installing a PRE2 Module

Note To ensure proper operation, always install

a single PRE2 in slot A. If you are installing a redundant PRE2 in slot B, wait until after you have installed and configured the primary PRE2 in slot A.

Equipment

ESD wrist strap Replacement PRE2 modules

Step 1 Ensure that you are properly grounded. Step 2 Inspect the connectors on both the PRE2

and the backplane. Bent or broken pins can cause a system malfunction.

Step 3 Carefully align the PRE2 module with the

guides in slot A in the chassis.

Step 4 Slide the module into the slot until you can

feel it seat in the backplane.

Step 5 Simultaneously close the ejector levers to

firmly seat the PRE2 in the backplane.

Step 6 Tighten the captive screws. Step 7 Reconnect all the cables to the PRE2 and

connect to the console.

Step 8 If you saved files to the old media card,

replace the new media card with the old media card.

Step 9 Power on the router. The PRE2 cycles

through its power-on self-test. The FAIL LED stays on briefly, goes off, and then boots into ROMMON mode.

Step 10 Boot the full image (if available) from the

media card or from the TFTP server. If the full image is not available, boot the

helper image from the onboard boot flash. After booting the router prompts for an initial configuration dialog.

Step 11 If you need to access the TFTP server to

obtain the full image or the saved configuration files, enter the configuration dialog and provide the information necessary to access the TFTP server.

If you booted the full image, restore the startup configuration and running configuration information, and set the boot variable for the new image. The upgrade is now complete.

If you booted from the helper image, download the full image, restore the startup and running configuration information, set the boot variable to the new image, and reload the router. The upgrade is now complete.

Installing a Redundant PRE2

Step 1 Repeat Step 1 through Step 8 for slot B. Step 2 From the console ROMMON prompt, set

the configuration to boot the full image and reload.

3 Troubleshooting

The PRE2 goes through a specific LED sequence at startup.

1. The FAIL LED briefly comes on and then goes off, and the STATUS LED starts flashing and progress messages appear on the PRE2 display .

2. IOS RUN appears after a successful bootup.

3. The STATUS LED on the PRE2 turns green.

4. The redundant PRE2 boot sequence is similar,

except that the STATUS LED remains off and the final message is IOS STBY, indicating that the PRE2 is in standby state.

If this sequence does not occur, the ST A T US LED is off, or the FAIL LED is yellow, check the following:

1. Are

the LEDs on other modules on? If not,

check for a problem in the power subsystem.

2. If other module’s LEDs are on, remove the PRE2 from the slot, check for bent or broken pins on the connectors, and reinsert it. Ensure that there is solid contact with the backplane and that the PRE2 is securely locked in place.

3. Verify the s tatus of the PRE2 module’ s internal Ethernet interface (ethernet0/0/0). If this internal interface is down, it could indicate that the PRE2 is not fully seated in the slot or that a hardware failure has occurred. Do not confuse the PRE2 internal Ethernet interface (ethernet 0/0/0) with the module’s external Fast Ethernet interface (fastethernet 0/0/0), which is used for network management and remote access.
