Removing and Replacing the System Board
The following procedures describe how to remove and replace the system board from the server
blade. When a system board fails, you must remove the following components from the failed
system board (unless they caused the failure), and install them on the new system board:
• SAS disk drives
• Memory DIMMs
• Processors
• SAS backplane
• Mezzanine cards
• TPM
CAUTION: Electrostatic discharge can damage electronic components. Ensure you are properly
grounded before beginning any removal or installation procedure.
For more information, see the “Safety Information” (page 26).
