No system power (FPGA heartbeat LED off)OffOffOffOffOffIf the AC power is on, but the system board assembly does not have power, then:

  1. Check the power supply unit (PSU), power interposer board (PIB), or power distribution board (PDB). If the PSU, PIB, or PDB has any error, replace it.

  2. If the PSU, PIB, or PDB is good, do the following:

    1. Replace the system I/O board.

    2. Replace the lower processor board (MB).

    3. Replace the upper processor board (CPU BD).
