Note- Inactive /cold maintenance can be performed only for a building block configuration.
Theinactive/cold maintenancepr ocedure for a single-chassis configuration is the same as
thatfor sto pping the system.
Note- In the case of a dual power feed, connect the power cords in their original positions by
referringto the record that you made before the start of maintenance.
For details, see "6.1 Incorporating an FRU into the System with the replacefru
Command."
3. Execute the diagxbu command to diagnose the crossbar cables.
Diagnosisis performed when the system board of the chassis connected with the
crossbar cables is incorporated into the physical partition, and the physical
partitionis powered on.
Theexa mple below specifies the following:
00:BB-ID of the chassis to start the diagnosis
02:P PAR-ID of the destination where the chassis to start the diagnosis is
connected (You can specify only one of these.)
4. Executethe showlogs command to confirm that the system is operating
normally.
For details, see "3.3.5 Checking log information."
5. Incorporatethe chassis, in which the PSU backplane unit requiring
maintenanceis mounted, into the physical partition.
For details, see "6.2 Incorporating a Chassis into a Physical Partition."
6. Closethe rack door.
