Replace the Power Supply Backplane Board (FRU)
“Remove a PCIe Card” on page 161
Make a note of where each PCIe card installed so they can be put back in the same slots. The
internal SAS/SATA cables and NVMe cables do not need to be removed, but must be out of the
way as the motherboard needs to be removed.
5.
If the server has only two CPUs, remove the air baffle.
The air baffle simply lifts straight up and out of the system. It is not attached to anything.
6.
Remove all memory riser cards.
“Remove a Memory Riser Card” on page 145
7.
Disconnect the fan board power and data cables from motherboard.
These cables do not need to be removed from the system and can remain plugged into the fan
board. However, care must be taken not to damage these cables when removing or inserting the
motherboard.
8.
To disconnect the power supplies from the backplane connectors, remove or
pull both power supplies at least part way out of the chassis.
“Remove a Power Supply” on page 137
.
9.
Move the air divider.
The air divider separates the disk drive backplane area from the rest of the chassis and includes
the system Fault Remind button mechanism. It must be moved to allow access to the power
supply backplane board and allow removal of the motherboard. The air divider is mounted to
the power supply side wall using two tabs that are inserted into slots in the side wall. For this
procedure, you can leave the cables attached to the air divider.
