About this task
Some field replaceable units (FRUs) are redundant and hot swappable, such as
power supplies. When replacing a hot-swap FRU, you have the option of leaving
the file module turned on and the power cables connected. Always follow the
remove and replace procedure for the FRU. The procedure for the FRU indicates
whether the FRU is hot swappable.
If the removal and replacement procedure does not indicate whether the FRU is
hot swappable, assume that it is not. In that case use the file module-removal
procedure that requires you to disconnect the power cords.
Note: Before removing an file module, you must suspend the file module.
Procedure
v Remove a file module from the system to replace a hot swappable FRU, as
