order:
1. Processor card
2. Memory modules in odd numbered slot (J1, J3, J5, etc.)
3. Memory modules in even numbered slot (J2, J4, J6, etc.)
4. Memory card
5. System board
6. I/O board (see notes on page 2-1.)
7. Power supply.

Turn the power on.
Does the system stop with code E1F2, E1F3, STBY or 4BA00830 displayed on
the operator panel?
NO Reinstall the original FRU.
Repeat the FRU replacement steps until the defective FRU is identified or
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
