Administratively Disabling the Fabric Plane

Please note that these steps are to be performed for each Cisco Crs-3 Fabric Card one at a time. When
one Fabric Node has completed the downgrade process we should come back to this step for the next
Fabric Node, until all 8 Fabrics have been downgraded.
As a first step in the downgrade process, we administratively shutdown the fabric plane that is to be
downgraded. This takes the fabric out of traffic operation, the router now continues to forward traffic on
the remaining 7 planes – there should not be any traffic drop.

RP/0/RP0/CPU0:router(admin)#config
RP/0/RP0/CPU0:router(admin-config)#controller fabric plane 0 shut
RP/0/RP0/CPU0:router(admin-config)#commit
Verify that fabric plane is now Admin-state Down.

Power Disable the Cisco CRS-3 Fabric Card

Next, we disable power to the Fabric node, and verify that node is moved to "UNPOWERED" state.
