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.
