Step 1540-17
The last FRU installed or one of its attached devices is probably defective.
1. Make sure the diagnostic CD-ROM disc is inserted into the CD-ROM drive.
2. Turn the power off and remove the power cable.
3. Starting with the last installed adapter, disconnect one attached device and
cable.
4. Plug in the power cable (and wait for OK on the operator panel display)
5. Turn the power on.
6. If the Console Selection screen is displayed, choose the system console.
7. After the keyboard indicator is displayed, press the F5 key on the
directly-attached keyboard or the number 5 key on an ASCII terminal keyboard.
8. Enter the appropriate password if prompted to do so.
Is the "Please define the System Console" screen displayed?
NO 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 unitis 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).
3. Power supply
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
2-32 in this MAP and follow the instructions for the new symptom.
YES The last device or cable that you disconnected is defective.
Exchange the defective device or cable.
