9.1 XSCF Unit Replacement
The XSCF unit is a cold replacement component. This means the entire server must
be powered off and the power cords disconnected to replace the XSCF unit.
Note – If you replace the XSCF unit and the operator panel simultaneously, system
will not operate normally. Execute the showhardconf command or the
showstatus command to confirm that the component replaced earlier is operating
normally, before replacing the subsequent FRU.
