14. Remove the fans, as described in “Removing a hot-swap fan” on page 133.
15.
Remove the fan bracket, as described in “Removing the fan bracket” on page
95.
16. Disconnect all cables from the system board.
Attention: In the following step, do not allow the thermal grease to come in
contact with anything, and keep each heat sink paired with its microprocessor
for reinstallation. Contact with any surface can compromise the thermal grease
and the microprocessor socket; a mismatch between the microprocessor and
its original heat sink can require the installation of a new heat sink instead.
17. Remove each microprocessor heat sink and microprocessor; then, place them
on a static-protective surface for reinstallation, as described in “Removing a
microprocessor and heat sink” on page 140.
18. Push in and lift up the two system board release latches on either side of the
fan cage.
19.
Slide the system board forward and tilt it away from the power supplies.
Using the lift handle, pull the system board out of the server.
20. If you are instructed to return the system board, follow all packaging
instructions, and use any packaging materials for shipping that are supplied
to you.
Installing the system board
The following procedure is for a field replaceable unit (FRU). FRUs must be
installed only by trained service technicians.
You must remove and replace the microprocessors when you replace the system
board. Ensure that you have alcohol wipes (part number 59P4739) and thermal
grease (part number 41Y9292) available to correctly perform this task. If you do not
already have the parts, order them separately.
To reinstall the system board, complete the following steps.
1. Install the Ethernet daughter card.
2. Align the system board as tilted shown, then rotate and lower it flat and slide
it back toward the rear of the server.
3. Reconnect to the system board the cables that you disconnected in step 16 of
“Removing the system board” on page 149.
When you reassemble the components in the server, route all cables carefully
so that they are not exposed to excessive pressure.
