Step 1540-3
One of the FRUs remaining in the system unit is defective.
If the following steps call for a I/O board to be replaced, see notes on page 2-1.
Turn the power off, remove the power cable, and exchange the following FRUs in
order:
1. Processor cards
2. Memory modules (pair)
3. Memory card
4. Fan monitor control card
5. I/O board (see notes on page 2-1)
6. System Board
7. Service Processor
8. Power distribution board.
Wait for the operator panel to stabilize at a checkpoint.
Note: Checkpoints E1F2, E1F3 and STBY are stable as soon as they appear.
Other checkpoints may take up to 3 minutes to assure stability, depending on system
configuration.
Does the operator panel stabilize with code E1F2, E1F3, E1F7, or STBY?
NO
Reinstall the original FRU.
Repeat the FRU replacement steps 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 1540-1” on
page 2-26 in this MAP and follow the instructions for the new symptom.
YES
Go to "MAP 410: Repair Checkout" in the
