This publication contains instructions for installing and configuring the Cisco Performance Routing Engine (PRE) module in a Cisco 10000 Edge Services Router (ESR). If you are not familiar with the Cisco 10000 router, see the Cisco 10000 ESR System Description, and the Cisco 10000 ESR Hardware Installation Guide for additional information.
The following sections are included in this configuration guide:
The Cisco 10000 ESR Performance Routing Engine (PRE) provides the high performance Layer 3 processing required to support advanced IP services such as QoS, access lists, and MPLS to thousands of T1 chassis connections (Figure 1).
The PRE contains two main printed circuit board assemblies:
All of the high performance processing engines in the PRE are based on advanced application specific integrated circuits (ASICs). These ASICs direct traffic at wire speed to and from the router line cards.
The front panel on the PRE contains three ports with RJ-45 connectors (see Figure 1):
Two PCMCIA Type II card slots can store the Cisco IOS image or a system configuration file on a Flash disk memory card. The system can also boot from the software stored on the Flash disk memory card.
LEDs on the front panel of the PRE provide a visual indication showing the status of PRE operation. The LEDs are separated into three categories: alarms, status, and failure.
See Figure 11 for a complete description of the PRE LEDs.
Before you perform any of the procedures in this guide, Cisco recommends that you:
Before you begin the PRE installation procedure, review the safety guidelines in this section to avoid injuring yourself or damaging the equipment. Before you install, configure, or perform maintenance on the router, you should also review the safety warnings listed in the Cisco 10000 ESR Hardware Installation Guide.
Safety warnings appear throughout this publication in procedures that, if performed incorrectly, may harm you. A warning symbol precedes each warning statement. The following warning is an example of a safety warning. It identifies the warning symbol and associates it with a bodily injury hazard.
 |
Warning This warning symbol means danger. You are in a situation that could cause bodily injury. Before you work on any equipment, be aware of the hazards involved with electrical circuitry and be familiar with standard practices for preventing accidents. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
 |
Note If you need translations of the safety warning, see the Cisco 10000 ESR Hardware Installation Guide. |
The PRE is compatible with any Cisco 10000 router operating with Cisco IOS Release 12.0(9)SL system software. Use the show version command to display the system software version that is currently loaded and running.
If the displays indicate that the running system software is a version earlier than Cisco IOS Release 12.0(9)SL, check the contents of Flash memory to determine if the required images are available on your system. The show flash command displays a list of all files stored in Flash memory. If the correct software version is not installed, contact Cisco Customer Service (see the "Cisco Connection Online" section).
This section contains guidelines for the following:
The Cisco 10000 system is hot-swappable which means you can remove and replace a PRE while the system is operating---if you have a secondary (redundant) PRE installed in the chassis. This feature allows you to add, remove, or replace a PRE, while the system maintains all routing information and ensures session preservation.
 |
Caution Replacing the primary PRE in a non-redundant chassis (no secondary PRE) causes a system shutdown and stops all traffic. If possible, alert all subscribers that the system will not be functioning during the replacement. |
|
Caution To prevent (electrostatic discharge) ESD damage, handle the PRE by the faceplate or the card carrier edges only. Avoid touching the printed circuit board and its components, or any connector pins. |
If you are replacing the PRE in a non-redundant system, you must configure the PRE using the configure command. For configuration information, refer to the "Configuring the PRE" section.
If the PRE is replaced in a redundant system containing two PREs, the secondary (or newly installed) PRE automatically assumes the configuration of the primary PRE; do not configure the new PRE.
You need the following tools and equipment to install the PRE:
This section describes how to install or replace the PRE in the Cisco 10000 chassis. It contains the following procedures:
Use the following procedure to remove the front cover from the system. If your system does not use a front cover, go to the "Installing a PRE" section.
Repeat this procedure for all four bezel plugs and then remove the plugs.
Step 2 Remove the cover by lifting it up slightly and then pulling it toward you (Figure 3).
Use the following procedure to install the PRE into slot 0A or slot 0B in the Cisco 10000 chassis.
|
Note If you are replacing a PRE, see the "Removing a PRE" section before you begin this procedure. |
Step 2 Grasp the faceplate of the PRE with one hand and place your other hand under the module (to support the weight of the module). Position the PRE in front of the chassis slot.
Step 3 Carefully align the upper and lower edges of the PRE with the upper and lower guides in the chassis, and slide the PRE into the slot until you can feel it begin to seat in the backplane connectors (Figure 5).
Step 4 Simultaneously pivot both ejector levers toward each other (until they are parallel to the faceplate) to firmly seat the PRE in the backplane (Figure 6).
The PRE cycles through its power-on self-test. The Fail LED stays on briefly (10 to 15 seconds) and then shuts off. If the Fail LED remains on, go to the "Troubleshooting the Installation" section.
Step 5 Secure the PRE in the chassis by tightening the top and bottom captive screws (Figure 7).
|
Caution To ensure that there is adequate space for additional line cards, always tighten the captive screws on each newly installed PRE before you insert a secondary PRE or any additional line cards. The captive screws prevent accidental removal and provide proper grounding for electromagnetic interference (EMI) shielding. |
Step 6 Refer to the "Configuring the PRE" section for information about configuring the PRE if necessary.
|
Note You do not need to configure a secondary PRE. The secondary PRE automatically assumes the configuration of the primary PRE. |
After the PRE is successfully installed, you can configure it for network use. For information about configuring the PRE, see the Cisco 10000 ESR Software Configuration Guide.
|
Note You do not need to configure a redundant (secondary) PRE. The secondary PRE automatically assumes the configuration of the primary PRE. |
Use the following procedure to remove a PRE from the chassis:
Step 2 Loosen the top and bottom captive screws on the PRE (Figure 9).
Step 3 Simultaneously pivot both ejector levers away from each other to disengage the PRE from the backplane (Figure 10).
Step 4 Slide the PRE out of the slot and place it on an antistatic surface, or in an antistatic bag.
Step 5 See the "Installing or Replacing the PRE" section for instructions to install a new PRE.
If you are not installing a replacement PRE, install a blank faceplate in the slot.
|
Warning Do not operate the system unless all slots contain a PRE, line card, or a blank faceplate. Blank faceplates are necessary in empty slots to prevent exposure to hazardous voltages, to reduce electromagnetic interference (EMI) that may disrupt other equipment, and to direct the flow of cooling air through the chassis. |
Refer to Figure 11 for descriptions of the LEDs on the OC-12 POS line card. Follow the instructions in Table 1 on the next page to troubleshoot the installation.
| Symptom | Possible Cause | Corrective Action |
|---|---|---|
Power entry modules (PEMs), fans, and other line cards do not operate | 1. Disconnected power cord. 2. Power switch is in the Off position. | 1. Check that all power cords are properly connected to both the Cisco 10000 system and at the power connection end. 2. Set the PEM power switches to the On position. |
The Fail LED does not light during the power-on self-test | 1. The PRE is not properly seated. 2. Bad PRE slot or backplane connector. | 1. Be sure the ejector levers are fully closed and that the captive screws have been tightened. 2. Remove the PRE and install it in another chassis slot. |
