Note -
Inactive/cold maintenance can be performed only for a building block configuration.
The inactive/cold maintenance procedure for a single-chassis configuration is the same as
that for stopping the system.
Note -
In the case of a dual power feed, connect the power cords in their original positions by
referring to 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.
Diagnosis is performed when the system board of the chassis connected with the
crossbar cables is incorporated into the physical partition, and the physical
partition is powered on.
The example below specifies the following:
00: BB-ID of the chassis to start the diagnosis
02: PPAR-ID of the destination where the chassis to start the diagnosis is
connected (You can specify only one of these.)
4.
Execute the showlog s command to confirm that the system is operating
normally.
For details, see "3.3.5 Checking log information."
5.
Incorporate the chassis, in which the PSU backplane unit requiring
maintenance is mounted, into the physical partition.
For details, see "6.2 Incorporating a Chassis into a Physical Partition."
6.
Close the rack door.
14.6.2 Inactive/Cold maintenance
1.
Connect all the power cords to the PSU backplane unit of the chassis
requiring maintenance.
For details, see "6.5.1 Installing the power cord."
2.
Return to the operation of the XSCF firmware replacefru command to confirm
that the chassis has been incorporated into the system.
For details, see "6.1 Incorporating an FRU into the System with the replacefru
Command."
