2. Reconnect the system console.
Notes:
a. If an HMC has been defined as the firmware console, attach the HMC cable to the HMC1
connector on the rear of the system unit.
b. 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.
c. If a display attached to a display adapter has been defined as the system console, install the
display adapter and connect the display to the adapter. Plug the keyboard into the keyboard
connector on the rear of the system unit.
3. Turn on the power.
4. If the ASCII terminal or graphics display (including display adapter) is connected differently than it was
previously, the console selection screen appears and requires that a new console be selected.
5. When the word keyboard is displayed, press the number 1 key on the directly attached keyboard, an
ASCII terminal or HMC. This activates the system management services (SMS).

One of the FRUs remaining in the system unit is defective.
Exchange the FRUs that have not been exchanged, in the following order:
1. If you are using the hardware management console (HMC) go to the "Entry MAP" in the
Hardware Management Console Maintenance Guide, order number SA38-0603. If you cannot
fix the problem using the HMC tests, there may be a problem with the CEC backplane. If you
do not find a problem, replace the CEC backplane, location U0.1-P1. (See notes on page 41.)
2. If you are using a graphics display, go to the problem determination procedures for the display.
If you do not find a problem, do the following:
v Replace the display adapter.
v Replace the backplane in which the graphics adapter is plugged.
Repeat this step until the defective FRU is identified or all the FRUs have been exchanged.
