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 there are any major alarms:
