Information About Bringing Up a Multishelf System

The following sections provide information that is good to know before you bring up a multishelf

system:

•Bringup Overview, page 3-3

•Preparing a Rack Number Plan, page 3-3

Bringup Overview

The bringup procedure for a multishelf system starts after the hardware installation is complete. The

bringup procedure tasks configure the system components to work together and verify the operat ion and

configuration of system components. To bring up the multishelf system, complete the following

procedures in the sequence shown:

1. Configuring the External Cisco Catalyst 6509 Switches, page 3-8

2. Bringing Up and Configuring Rack 0, page 3-28

3. Bringing Up and Verifying FCCs, page 3-34

4. Bringing Up and Verifying the Non-DSC LCC, page 3-37

5. Verifying the Spanning Tree, page 3-39

During the bringup procedure, you need the information presented in the following section.

Preparing a Rack Number Plan

In a multishelf system, each chassis must be assigned a unique rack number, as shown in Figure3-1. Th is

rack number is used to identify a chassis in the system, and maintain the software and configurations for

the chassis.

Caution Failure to assign a unique rack number to each chassis in the system can result in serious system error

and potential downtime. Unique rack numbers must be assigned and committed on Rack 0 before the

additional chassis are powered on and brought on line.
