Step 1540-11
The last FRU installed or one of its attached devices is probably defective.
1. Make sure the diagnostic CD-ROM 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. Reinstall the power cable.
5. Turn the power on.
6. If the Console Selection screen is displayed, choose the system console.
7. After the keyboard indicator appears, press the F5 key on the directly-attached
keyboard or the number 5 key on an ASCII terminal keyboard.
8. 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 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 planar
If the I/O planar or a network adapter is replaced, 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 2-18 in this MAP and follow the instructions for the new symptom.
YES The last device or cable that you disconnected is defective or if the last
device is the CPU card go to “Step 1540-3” on page 2-20.
Exchange the defective device or cable.
