Step 1540-27
The last FRU installed or one of its attached devices is probably defective.
1. Turn the power off and remove the power cable from the power outlet.
2. Starting with the last installed adapter, disconnect one attached device and
cable.
3. Plug in the power cable (and wait for OK on the operator panel display).
4. Turn the power on.
5. If the Console Selection screen displays, choose the system console.
6. Enter the appropriate password if prompted to do so.
Does the system stop with the same error code displayed on the operator
panel that directed you to this MAP step?
NO The last device or cable that you disconnected is defective.
Exchange the defective device or cable.
Go to "MAP 410: Repair Checkout" in the
IBM RS/6000 Diagnostic
Information for Multiple Bus Systems
.
YES Repeat this step until the defective device or cable is identified or all the
devices and cables have been disconnected.
If all the devices and cables have been removed, then one of the FRUs
remaining in the system is defective.
To test each FRU, exchange the FRUs in the following order:
1. Adapter (last on installed)
2. I/O board (see notes on page 2-1).
If the symptom did not change and all the FRUs have been exchanged,
go to “Step 1540-2” on page 2-33.
