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 power-on switch on the operator panel to turn on the power 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 power-on switch on the operator panel to turn on the power.
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
service support 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 46 in
this MAP and follow the instructions for the new symptom.
