Step 1520-7
Either the processor card, system board, I/O board or power supply is defective.
To test each FRU, exchange the FRUs that have not already been exchanged in the
following order:
1. Processor card
2. System board
3. I/O board
4. Power supply.
Press the start/stop switch on the operator panel to turn the power on after each
FRU is exchanged. If the power stays on, the most recently exchanged FRU was
causing the failure.
1. Unplug the power cord from the system unit.
2. Exchange one of the FRUs in the list.
3. Plug the power cord into the system unit.
4. Press the start/stop switch on the operator panel to turn the power on.
Does the power LED on the operator panel come on and stay on?
NO Reinstall the original FRU.
Repeat this step until the defective FRU is identified or all the FRUs have
been exchanged.
If the symptom did not change and all the FRUs have been exchanged,
call your service support person for assistance.
If the symptom has changed, check for loose cards, cables, and obvious
problems. If you do not find a problem, return to “Step 1520-1” on page
2-24 in this MAP and follow the instructions for the new symptom.
