system board, are firmly seated.
• Check that the system board is fully seated in its card edge connector and
that the seating lever between the system board and the chassis is fully
closed.
• Check that the primary CPU module is fully seated in the lower (primary)
CPU socket on the system board. Check that the processor seating levers
are closed.
