Removing the system board
Use this information to remove the system board.
Before you remove the system board from the server, take the following steps to
save data, firmware, and configuration data:
v Record all system configuration information, such as IMM IP addresses, vital
product data, and the machine type, model number, serial number, Universally
Unique Identifier, and asset tag of the server.

on a CD or DVD image. Make sure that you have the latest firmware or a copy of
the pre-existing firmware before you proceed.
