Preparing to Upgrade the SIBs

To prepare to upgrade the SIBs, follow this procedure:

1.The T640 routing node must contain five standard SIBs or SIBs version B before the upgrade. Verify that four SIBs are in the Online state and one SIB is in the Spare state. Display the status of the SIBs by issuing the show chassis sibs command:

user@host> show chassis sibs

To bring a SIB online, issue the request chassis sib online operational mode command. To install additional SIBs, use the standard installation procedure described in the T640 Internet Routing Node Hardware Guide.

NOTE: Do not proceed with the upgrade until all five SIBs are present and operational.

2.Enter configuration mode.

user@host> configure

3.Include the fabric upgrade-modestatement in the configuration at the [edit chassis] hierarchy level.

user@host# set chassis fabric upgrade-mode

4.Commit the configuration:

If GRES is enabled, commit the configuration on both the master and the backup Routing Engines:

user@host# commit synchronize

If GRES is not enabled, commit the configuration on the master Routing Engine:

user@host# commit

5.Exit configuration mode.
