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 and install them on the new system board, unless they caused the failure:
• SAS disk drives
• Memory mezzanine board
• Processors and power connectors
• Mezzanine cards
• SAS backplane and cable
• Front panel
• TPM
• Air baffles
CAUTION: Electrostatic discharge can damage electronic components. Ensure you are properly
grounded before beginning any removal or installation procedure.
For more information, see “Safety Information” (page 26).
