The system is working correctly with this configuration. One of the FRUs (adapters)
that you removed is probably defective.

2. Turn the power off and remove the power cables.

6. 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.

Is the "Please define the System Console" screen displayed?

In the following order, exchange the FRUs that have not been exchanged.
1. Diskette drive
2. Diskette drive cable
3. I/O board (see notes on page 2-1).

Repeat this step until the defective FRU is identified or all the FRUs have
been exchanged.

call your service support person for assistance.

problems. If you do not find a problem return to “Step 1540-1” on
