This procedure can also be completed as a cold service procedure.
Identify the CMOD.
If you are removing a CMOD in a failed state, the lit fault indicator for
the CMOD on the FIM shows you the CMOD number and the group to which it
belongs.
Identify which group of fan modules (left or right) to remove to access
the CMOD.
For CMODs 0-3 access, remove the left FM group. For CMODs 4-7 access,
remove the right FM group.
Tip:
If you know the group, then you know which group of four fan modules to remove from the front panel.
