Remove the system board

Use this information to remove the system board.

About this task

A system board 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. Before removing the system board, record all system configuration information, such as Lenovo XClarity Controller (XCC) IP addresses, vital product data, and the machine type, model number, serial number, Universally Unique Identifier, and asset tag of the server.
