v If you are removing an adapter from PCI expansion slot 1 or 2, remove PCI
riser-card assembly 1.
v If you are removing an adapter from PCI expansion slot 3 or 4, remove PCI
riser-card assembly 2.
8. Remove the SAS controller assembly, which includes the SAS riser card, from
the server, as described in "Removing the SAS riser-card and controller
assembly" on page 117.
9. If an Ethernet daughter card is installed in the server, remove it.
10. If a virtual media key is installed in the server, remove it, as described in
"Removing the IBM virtual media key" on page 103.
11. Remove the DIMM air baffle, as described in "Removing the DIMM air baffle"
on page 98.
12. Remove the microprocessor 2 air baffle, as described in "Removing the
microprocessor 2 air baffle" on page 95.
13. Remove all DIMMs, and place them on a static-protective surface for
reinstallation, as described in "Removing a memory module" on page 138.
Important: Note which DIMMs are in which connectors, before you remove
the DIMMs. You must install them in the same configuration on the
replacement system board.
14. Remove the fans, as described in "Removing a hot-swap fan" on page 141.
15. Remove the fan bracket, as described in "Removing the fan bracket" on page
100.
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 148.
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.
Before you begin
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.
