Step 1540A-12
1. Make sure the diagnostic CD-ROM disc is inserted into the CD-ROM drive.
2. Turn the power off.
3. Starting with the last installed adapter, if there are any devices and cables
attached to it, disconnect one attached device and cable.
4. Turn the power on.
5. If the Console Selection screen is displayed, choose the system console.
6. After the keyboard indicator begins blinking, press the F5 key on the
directly-attached keyboard or the number 5 key on an ASCII terminal keyboard.
7. Enter the appropriate password when prompted to do so.
Is the "Please define the System Console" screen displayed?
NO Repeat this step until the defective device or cable, if any were attached,
is identified or all the devices and cables have been disconnected.
If all the devices and cables have been removed, or there were none
attached, 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. Riser card
3. System board
4. Power supply
If a network adapter or system board is replaced, see notes on page 2-1.
If the symptom did not change and all the FRUs have been exchanged,
call your service support person for assistance.
Repeat this step until all of the FRUs have been exchanged.
If the symptom has changed check for loose cards, cables, and obvious
problems. If you do not find a problem return to “Step 1540A-1” on
page 2-22 in this MAP and follow the instructions for the new symptom.
YES The last device or cable that you disconnected or the last FRU that you
exchanged is defective.
Exchange the defective FRU, device or cable.
