Upgrading the Switch Fabric

Upgrade Requirements

Before proceeding, review the following upgrade requirements:

1. You must have a complete switch fabric card set. You cannot intermix 2.5-, 10-, and 40-Gbps CSCs

and SFCs.

2. When upgrading to a 10-Gbps switch fabric with a GRP installed, the Flash memory card must be

loaded with Cisco IOS Release 12.0(16)S or later.

3. When upgrading to a 10-Gbps switch fabric with a PRP installed, the Flash memory card must be

loaded with Cisco IOS Release 12.0(22)S or later.

4. When upgrading to a 40-Gbps switch fabric, the Performance Route Processor (PRP) must be

installed, and the flash memory card must be loaded with Cisco IOS Release 12.0(31)S or later.

5. When upgrading to an enhanced 10-Gbps switch fabric, the Performance Route Processor (PRP)

must be installed, and the flash memory card must be loaded with Cisco IOS 12.0(32)SY2 or later.

6. When upgrading to an enhanced 40-Gbps switch fabric, the Performance Route Processor (PRP)

must be installed, and the flash memory card must be loaded with Cisco IOS 12.0(31)S or later.

Upgrading the Switch Fabric

To upgrade the switch fabric, follow these steps:

Step 1 Turn off power to the router.

Step 2 Remove all CSCs and SFCs. See the “Removing a Card from the Switch Fabric and Alarm Card Cage”

section on page 11.

Step 3 Install the new CSCs and SFCs. See the “Installing a Card in the Switch Fabric and Alarm Card Cage”

section on page 13.

Note Although they perform similar functions, you cannot intermix SFCs and CSCs. The switch fabric

is a card set. You must use either the 10- or 40-Gbps switch fabric card set.

Step 4 Insert a Flash memory card into the PRP, making sure that it is loaded with the appropriate

Cisco IOS release, noted in the “Upgrade Requirements” section on page 20.

Step 5 Turn on power to the router and wait for all installed line cards to fully boot before proceeding to the

next step.

Note Let the router return to full operation before proceeding to the next step. This may take a

considerable amount of time depending upon the configuration of the router.

Step 6 At the privileged EXEC prompt, enter the configure terminal command to enter global configuration

mode.

Step 7 Enter the service upgrade mbus-agent-rom command.

Step 8 Enter the service upgrade fabric-downloader command.

Step 9 After the commands have finished running, press Ctrl-Z to exit configuration mode.
