Notes:
a. If a terminal attached to S1 or S2 is the system console, plug the terminal
cable into the S1 or S2 connector on the rear of the system unit.
b. If a display attached to a display adapter is the system console, install the
display adapter and connect the display to it. Plug the keyboard into the
keyboard connector on the rear of the system unit.

NO One of the FRUs remaining in the system unit is defective.
In the following order, exchange the FRUs that have not been exchanged:
1. Go to the Problem Determination Procedures (test procedures) for the
device attached to the SIO serial port or the display attached to the
graphics adapter, and test those devices. If a problem is found,
follow the procedures for correcting the problem on that device.
2. Graphics adapter (if installed).
3. Cable (async or graphics).
4. System board.
Repeat this step until the defective FRU is identified or all the FRUs have
been exchanged.
If the symptom did not change and all the FRUs have been exchanged,
call your service support person for assistance.
