Step 1540-3
One of the FRUs remaining in the system unit is defective.
Note: If the system stopped with a checkpoint or error code different from the one that
directed you to this MAP, perform the action indicated by the new checkpoint or
error code. If the new checkpoint or error code has no action indicated or the
action does not correct the problem, continue with this step.
1. Turn off the power, remove the power cable, and replace the FRUs, one at a time,
with new or previously removed FRUs in the following order:
a. Memory DIMMs quad A on memory riser card 1, if present, with new or
previously removed DIMMs.
b. Memory riser card (Location: P1-M1), if present, with a new or previously
removed memory riser card.
c. Memory riser card (Location: P1-M2), if present, with a new or previously
removed memory riser card.
d. Memory DIMMs pair A on one-way processor card, if present, with new or
previously removed DIMMs.
e. Processor card (Location: P1-C1)
f. Operator panel (Location: L1)
g. Operator panel cable
h. System board (Location: P1) (see note 3 on page 37)
2. Plug in the power cable and wait for OK in the operator panel display.
3. Turn on the power.
4. Wait for the operator panel to stabilize at a checkpoint.
Note: Checkpoints E1F2 and E1F3 are stable as soon as they appear. Other
checkpoints may take up to 3 minutes to ensure stability, depending on
system configuration.
Does the operator panel stabilize with code E1F2, E1F3, E1F7 or 20EE 000B?
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 53 in
this MAP and follow the instructions for the new symptom.
