Figure 91. Replace fan module
Replacing all fan modules
3. Repeat steps â1â on page 79 and â2â on page 79 for each fan module to be replaced.
4. Power on the expansion enclosure.
Installing or replacing a fan interface board: 2076-92F
You can replace a fan interface board (FIB) in a 2076-92F expansion enclosure.
Before you begin
This task assumes that the following conditions are met:
⢠You removed the fan interface board, following the process described in âRemoving a fan interface
board: 2076-92F â on page 100.
⢠All power cables were removed from the enclosure, as described in âPowering off the expansion
enclosure: 2076-92F â on page 115.
⢠The expansion enclosure is removed from the rack, as described in âRemoving an expansion enclosure
from a rack: 2076-92F â on page 83.
⢠A lift is supporting the weight of the enclosure.
⢠The top cover, fans, drives, and other heavy FRUs are removed from the enclosure.
About this task
The 2076-92F expansion enclosure contains two fan interface boards (FIBs). The FIBs act as the
interface between the fans and the system drive board. FIB 1 connects fan modules 1 and 2 to the drive
board; FIB 2 connects fan modules 3 and 4. If the fault LED on each fan module is lit, it is possible that
the FIB that controls those modules needs to be replaced. You can also issue the
lsenclosurefanmodule command to display the status of the fans.
If you removed the FIBs from a faulty expansion enclosure, you must reinstall them in the replacement
enclosure. Refer to the procedure described in âReplacing an enclosure: 2076-92F â on page 103.
Procedure
1. Assemble the new FIB, cover, and the cover screws (shown in Figure 92 on page 81) in a safe
location.
