v Using the Advanced Settings Utility (ASU), save the system configuration to
external media.
v Save the system-event log to external media.
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.
To remove the system board, complete the following steps:
1. Read the safety information that begins on page Safety and "Installation
guidelines" on page 30.
2. Turn off the server (see "Turning off the server" on page 21) and all attached
peripheral devices. Disconnect all power cords; then, disconnect all external
cables as necessary to replace the device.
3. Remove the server cover (see "Removing the server top cover" on page 362).
4. Remove the air baffle (see "Removing the air baffle" on page 365).
5. Remove all PCI riser-card assemblies with the adapters in them (see
"Removing a PCI riser-card assembly" on page 328).
6. Disconnect all cables from the system board. 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.
Attention: Disengage all latches, release tabs or locks on cable connectors
when you disconnect all cables from the system board. Refer to"Internal cable
routing" on page 276). for more information. Failing to release them before
removing the cables will damage the cable sockets on the system board. The
cable sockets on the system board are fragile. Any damage to the cable sockets
may require replacing the system board.
7. Remove the DIMMs from the system board and set them aside on a
static-protective surface for reinstallation (see "Removing a memory module"
on page 312).
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.
8. Remove all heat sinks and microprocessors, and set them aside on a
static-protective surface for reinstallation (see "Removing a microprocessor
and heat sink" on page 347).
Note:
a. Be sure to keep the heat sink and microprocessor from each
microprocessor socket of the old system board together so that you can
install them on the new system board together. For example, when you
remove the heat sink and microprocessor from microprocessor socket 1 of
the old system board , install them both on the same socket on the new
system board.
b. Use an alcohol wipe to remove any thermal grease from the tabs on the
microprocessor bracket frame on the old system board.
