Removing the system board
Use this information to remove the system board.
To remove the system board, complete the following steps.
Notes:
1. When you replace the system board, make sure that you remove the virtual media key and place it on
the new system board. For information about the location of the key, see
key" on page
469.
2. When you replace the system board, you must either update the server with the latest firmware or
restore the pre-existing firmware that the customer provides on a diskette or CD image. Make sure that
you have the latest firmware or a copy of the pre-existing firmware before you proceed.
Step 1.
Read the safety information that begins on
417.
Step 2.
Turn off the server and peripheral devices and disconnect the power cords and all external cables.
Step 3.
Remove the cover (see
Note: When you replace the system board, you must either update the server with the latest
firmware or restore the pre-existing firmware that the customer provides on a diskette or CD image.
Make sure that you have the latest firmware or a copy of the pre-existing firmware before you
proceed.
Step 4.
Pull the power supplies out of the rear of the server, just enough to disengage them from the server.
Step 5.
Remove all PCI riser-card assemblies and adapters (see
page
487).
Step 6.
Remove the SAS/SATA RAID riser-card assembly (see
assembly" on page
Step 7.
Remove the microprocessor 2 and DIMM air baffles from the system board (see
microprocessor 2 air baffle" on page 426
Step 8.
(Trained service technician only) Remove all heat sinks and microprocessors, and set them aside
on a static-protective surface for reinstallation (see
page
499).
a.
Remove the socket covers from the microprocessor sockets on the new system board and
place them on the microprocessor sockets of the system board you are removing.
b.
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.
Step 9.
Remove the memory modules and set them aside on a static-protective surface for reinstallation
(see
"Removing a memory module" on page
Note: Make a note of the location of each DIMM as you remove it, so that you can later reinstall it
in the same connector.
Step 10. Remove the virtual media key from the system board and set it aside. You will have to install the
virtual media key on the new system board.
Step 11. Remove the system battery (see
Step 12. Disconnect all cables from the system board (see
420). Make a list of each cable as you disconnect it; you can then use this as a checklist when you
install the new system board.
