Remove The System Board - Lenovo ThinkSystem SR630 Maintenance Manual

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 83 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.
