Maintenance Analysis Procedures (MAPs)
Step 3
(from Step 2)
One of the parts installed into the system unit is defective.
To test each part, exchange them in the following order:
1. System planar
2. CPU card
3. Memory card
4. Power supply
5. Operator panel
The system is working correctly if the maintenance menu is displayed. If this occurs, the last
part you exchanged is defective.
1. Power off the system.
2. Unplug the power cord.
3. Exchange one of the parts in the list.
4. Plug the power cord in.
5. Power on the system.
6. Wait for one of the following conditions to occur:
•
The Maintenance Menu is displayed.
•
The same three digit number is displayed in the operator panel display for longer than
three minutes except for the number
165
which may display for up to ten minutes with
no activity on the BUMP console.
•
The number
888
is flashing in the operator panel display.
Is the maintenance menu displayed?
NO
Reinstall the original part.
Repeat Step 3 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 1 in this MAP and
follow the instructions for the new symptom.
YES
The last FRU you exchanged is the defective one. Reinstall all the FRUs
you have exchanged, except the last one and power on the system. Go to
“Map 0410: Repair Checkout” in the
