Removing and Replacing the System Board
This section explains how to remove and replace the system board.
Removing the System Board
To remove the system board, follow these steps:
1. Turn off the system and disconnect all power and external cables.
2. Remove the system’s access panel(s) (refer to page 37 and page 41 for instructions).
3. Follow these steps:
a. Complete step three of the removal instructions found in the section “Removing
and Replacing Memory” on page 46.
b. Complete step three of the section “Removing an Accessory Card” on page 49.
c. Complete step three of the section “Removing a System Fan” on page 65.
d. Complete steps three through five of the section “Removing the Processor Airflow
Guide” on page 67.
e. Complete steps three through five of the section “Removing the Management
Card” on page 70. You can skip this step if your system does not have a
Management card.
4. Complete this step if your system does not have a Management card installed, and
you need to remove the power connectors; otherwise, skip to step 5. Unscrew the two
power connector mounting screws on the back of the system, and reach inside the
system to remove the power connectors from their slot. See Figure 2-65. The power
connectors will still be connected to their cables. You will just be moving them out of
the way so you can remove the system board.
