Note – It is advisable to connect an ASCII terminal to the system during installation. See Section 2.6, “Connecting an ASCII Terminal,” for terminal settings and connections.

Observe the yellow (middle) LED on the front panel. It should go off when boot completes. If it remains lit, observe the terminal screen for boot messages produced by the firmware diagnostic program during power on.

a.Turn the system key switch to (the Standby position). See Figure 3-1.

b.Turn the AC power sequencer power switch to Off.

The AC power sequencer is at the rear of the cabinet. See Figure 3-2.
