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:
Procedure
10. Remove the system battery (see "Removing the system battery" on page 209).
11. Remove the USB embedded hypervisor flash device (see "Removing a USB

external media.
1. Read the safety information that begins on page "Safety" on page vii and
"Installation guidelines" on page 32.
2. Turn off the server (see "Turning off the server" on page 22) and all attached
peripheral devices. Disconnect all power cords; then, disconnect all external
cables as necessary to replace the device.
3. Pull the power supplies out of the rear of the server, just enough to disengage
them from the server.
4. Remove the server top cover (see "Removing the server top cover" on page
258).
5. Remove the hot-swap rear hard disk drive cage (see "Removing the hot-swap
rear hard disk drive cage" on page 170.
6. Remove all PCI riser-card assemblies and adapters (see "Removing a PCI
riser-card assembly" on page 206, "Removing an adapter from the PCI
riser-card assembly" on page 179 and "Removing a ServeRAID adapter from
the PCI riser-card assembly" on page 190.
7. Remove the air baffle (see "Removing the air baffle" on page 261).
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 238.
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.
9. Remove all DIMMs, and place them on a static-protective surface for
reinstallation (see "Removing a memory module" on page 186).
Important: Make a note of the location of each DIMM as you remove it, so
that you can later reinstall it in the same connector.

disconnect it; you can then use this as a checklist when you install the new
system board (see "Internal cable routing" on page 164 and "System-board
internal connectors" on page 26 for more information).
