6. Turn the key switch at the front of the expansion cabinet to the On position
(
FIGURE 3-3
).
The expansion cabinet will power on approximately 20 seconds after the key switch
is turned on. This delay minimizes power surges.

Front Sequencer Status Lights
The three power status indicators on the front panel show the status of the front
power sequencer. The bottom LED will light as soon as power is applied to the
expansion cabinet. The LED for sequencer stage 1 will light, followed by the LED for
sequencer stage 2.
Note –
The bottom LED will not light unless the AC power sequencer circuit
breakers for the front power supply are on.
Note –
To check the status of the rear power sequencer, open the rear door of the
expansion cabinet and look at the three green LEDs on the rear power sequencer.
7. Turn the power on to the system cabinet.
See the installation manual you received with your system cabinet for instructions.
You may have to enter a specific software command when booting the system so
that the system will recognize the expansion cabinet.
See the software documentation for more information.
After power is turned on, several events occur:
■
The system will make a “beep” sound, indicating that the system is ready.
■
The terminal screen will illuminate once the internal self-test has been completed.
You may need to edit the configuration file for your devices. See the documentation
for the particular device, and the Solaris Handbook for Sun Peripherals for software
instructions.
