Step 1540-8
1. Turn off the power.
2. Reconnect the system console.
Notes:
a. If an HMC has been defined as the firmware console, attach the HMC cable to
the HSC1 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 before, 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).
6. Enter the appropriate password if you are prompted to do so.
Is the SMS screen displayed?
NO
