2. Reconnect the system console.
Notes:
a. If an ASCII terminal has been defined as the system console, attach the ASCII
terminal cable to the S1 connector on the rear of the system unit.
b. If a display attached to a display adapter has been defined as 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.
3. Turn on the power.

differently than before, the Console Selection screen appears and requires that a
new console be selected.
5. When the keyboard indicator is displayed, press the number 1 key on the directly
attached keyboard or the number 1 key on an ASCII terminal to start the SMS

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 S1 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, including internal async cable).
4. System board (see note 3 on page 41).
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.
If the symptom changed, check for loose cards and obvious problems. If you
do not find a problem, return to "Step 1540-1" on page 58 and follow the
