Remove the system board
Use this information to remove the system board.
About this task
A system board, also known as the motherboard, provides different connectors or slots to connect different
components or peripherals of the system for communication. If the system board fails, it must be replaced.
Attention:
• Read “Installation Guidelines” on page 27 to ensure that you work safely.
• Power off the server and disconnect all power cords for this task.
• Prevent exposure to static electricity, which might lead to system halt and loss of data, by keeping static-
sensitive components in their static-protective packages until installation, and handling these devices with
an electrostatic-discharge wrist strap or other grounding system.
Procedure
Step 1. Prepare your server.
a. Remove the top cover. See “Remove the top cover” on page 106.
b. If your server comes with an air baffle, remove it first. See “Remove the air baffle” on page 29.
c. If your server comes with a rear drive assembly, remove it first. See “Remove the hot-swap
rear drive assembly” on page 48.
d. Record where the cables are connected to the system board; then, disconnect all the cables.
Attention: Disengage all latches, cable clips, release tabs, or locks on cable connectors
beforehand. Failing to release them before removing the cables will damage the cable
connectors on the system board. Any damage to the cable connectors may require replacing
the system board.
e. Remove any of the following components that are installed on the system board and put them
in a safe, static-protective place.
