Step 1540-28
The last FRU installed or one of its attached devices is probably defective.
1. Turn the power off and remove the power cable.
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 is displayed, choose the system console.
6. Enter the appropriate password if prompted to do so.
Does the system stop with code 26800Dxx, 45800000, 4880090A, 4B2xxx00 or
4B2xxx10 displayed on the operator panel?
NO
The last device or cable that you disconnected is defective.
Exchange the defective device or cable.
Go to "Map 0410: Repair Checkout" in the Diagnostic Information for Mul-
tiple 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 unit is defective.
To test each FRU, exchange the FRUs in the following order:
1. Adapter (last one installed)
2. I/O board (See notes on page 2-1)
If the symptom did not change and all the FRUs have been exchanged,
return to “Step 1540-2” on page 2-39.
