Cisco 10000 Series Router Performance Routing Engine Installation

OL-3971-03

Installation Guidelines

The Cisco 10000 router 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.

New Installation Guidelines

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 on page 16.

Replacement Installation Guidelines

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.

Required Tools and Equipment

You need the following tools and equipment to install the PRE:

• A 3/16-inch flat-blade screwdriver

• An ESD-preventive wrist or ankle strap with connection cord

• A terminal console to connect to the PRE after it is installed

Removing the Cisco 10008 Front Cover

Use the following procedure to remove the front cover from the Cisco 10008 router.

• If your Cisco 10008 router does not have a front bezel, go to the “Powering Off the System” section

on page 11.

• If your Cisco 10008 router has a bezel with bezel plugs, go to step 1.

• If your Cisco 10008 router has a bezel without bezel plugs, go to step 2.
