The ServeRAID SAS controller (see “Removing the ServeRAID SAS
controller” on page 69)
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.
6. Remove all DIMMs, and place them on a static-protective surface for
reinstallation (see “Removing a memory module (DIMM)” on page 87).
7. Disconnect all cables from the system board.
8. Slide the power supplies out of the bays slightly or remove them entirely (see
“Removing a hot-swap power supply” on page 93).
Attention:
In a dc power environment, only trained service personnel other
than Lenovo service technicians are authorized to connect or disconnect power
to the dc power supply. See the documentation that comes with each dc power
supply.
9. Slide the power backplane toward the right side of the server (see “Removing
the power backplane” on page 104).
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.
10. Remove the VRM and each microprocessor heat sink and microprocessor;
then, place them on a static-protective surface for reinstallation (see
“Removing a microprocessor” on page 112).
11. Slide the shuttle release latch toward the left side of the server, and push the
shuttle toward the rear of the server approximately 12.7 mm (0.5 inch).
12. Lift the shuttle out of the server.
13. If you are instructed to return the system board and shuttle assembly, follow all
packaging instructions, and use any packaging materials for shipping that are
supplied to you.
Installing the system board and shuttle
Notes:
1. When you reassemble the components in the server, be sure to route all cables
carefully so that they are not exposed to excessive pressure.
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.
To reinstall the system board and shuttle, complete the following steps.
