Installing or replacing a fan interface board: 2077-92F
You can replace a fan interface board (FIB) in a 2077-92F 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 “Removing a fan interface
board: 2077-92F ” on page 96.
• All power cables were removed from the enclosure, as described in “Powering off the expansion
enclosure: 2077-92F ” on page 111.
• The expansion enclosure is removed from the rack, as described in “Removing an expansion enclosure
from a rack: 2077-92F ” on page 79.
• 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 2077-92F 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 “Replacing an enclosure: 2077-92F ” on page 99.
Procedure
1. Assemble the new FIB, cover, and the cover screws (shown in Figure 81 on page 77) in a safe
location.
