Problem Action
Power lights on the MCU
PCBA do not illuminate. 1. Verify connection of ac power cord.
2. Verify ac power is applied.
3. Verify the MCU is fully seated in the card rack.
4. Call for service of the applicable power supply.
Plug-in cards do not
operate in one of the slots. 1. Check slot with a known good plug-in card.
2. Call for service of the backplane PCBAs.
