Fabric plane details of all MPCs are also displayed.
7. Verify if the show chassis fabric summary command output shows fabric planes in the 'check' state.
This indicates that the fabric plane has an error. You can try to recover the fabric plane to normal
operation by issuing the request chassis fabric plane <#> offline command, followed by the request
chassis fabric plane <#> online command, where <#> equals the fabric plane in error.
NOTE: After you issue the request chassis fabric plane <#> offline and request chassis
fabric plane <#> online commands, issue the show chassis fabric summary command to
verify that the fabric plane errors are rectified and to verify the current state of the fabric
planes.
8. Verify if any major alarms are displayed:
user@host> show chassis alarms
Alarm Time Class Description
2011-06-01 13:37:43 EDT Minor Require a fan tray upgrade
2011-06-01 13:37:26 EDT Minor Backup RE Active
In this example, the major alarms are no longer displayed, and the upgrade is successfully completed.
9. Disable the upgrade configuration by issuing the set chassis state cb-upgrade off command and then
the commit command.
10. You can delete that command by issuing the delete chassis state cb-upgrade command and then the
commit command.
11. Verify the SCBE-MXs before you finish by issuing the show chassis hardware command:
user@host> show chassis hardware
