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. Make sure that
you have the latest firmware or a copy of the pre-existing firmware before you proceed. See
“Updating
the firmware” on page 513
, “Updating the Universal Unique Identifier (UUID)” on page 530, and
“Updating the DMI/SMBIOS data” on page 531 for more information.
Important: Some cluster solutions require specific code levels or coordinated code updates. If the device is
part of a cluster solution, verify that the latest level of code is supported for the cluster solution before you
update the code.
To install the system board, complete the following steps:
Step 1. Read the safety information that begins on
“Safety” on page v and “Installation guidelines” on page
417
.
Step 2. Align the system board with the chassis; then, lower the system board into the chassis and slide
the system board toward the rear of the server until the system board is seated firmly into the
locator pins on the chassis.

Step 3. Grasp the fan assembly brackets and rotate them down toward the chassis.
Step 4. Reinstall the hot-swap fans (see
“Installing a hot-swap fan assembly” on page 461).
Step 5. (Trained service technician only) Reinstall the microprocessor and heat sink (see
“Installing a
microprocessor and heat sink” on page 502
).
Step 6. Reinstall the SAS/SATA RAID riser-card assembly base (see
“Installing the SAS/SATA RAID riser-
card assembly” on page 451).
