11.3 Restarting the System
Note – As the system starts up, watch for error messages from the POST diagnostic
program. If a terminal is not already part of the system, you can install a TTY
terminal before continuing the startup. See Section 9.1 “Using a Terminal” on
page 9-1 for terminal settings.
1. The system key switch must be turned to (the standby position) (
FIGURE 11-1
or
FIGURE 11-3
).
Caution –
The outlet must be a 120-240 VAC 30-ampere circuit, intended solely for
use by the server cabinet, as described in the site preparation instructions in the Sun
Enterprise 6500/5500/4500 Systems Installation Guide. The electrical receptacle must be
grounded, and the grounding conductor serving this receptacle must be connected
to the earth ground at the service equipment.
2. Enterprise 6500/5500 systems only: turn the Local/Remote switch down, to
Local
(
FIGURE 11-2
).
3. Turn on the AC main power switch (
FIGURE 11-2
or
FIGURE 11-4
).
4. Turn on power to the terminal.
A terminal is optional for viewing system messages. For setup instructions, see
Section 9.1 “Using a Terminal” on page 9-1.
5. Turn the front panel key switch to (the power on position) (
FIGURE 11-1
or
FIGURE 11-3
).
Several things will happen:
■
The left front panel LED (green) turns on immediately to indicate the DC power
supply is functioning.
■
The middle front panel LED (yellow) lights immediately and should turn off after
approximately 60 seconds.
■
The right front panel LED (green) flashes after POST has ended to show that
booting is successful and the operating system is running.
■
The terminal screen lights up upon completion of the internal self-test.
Caution –
Never move the server or the expansion cabinets when system power is
on. Excessive movement can cause catastrophic disk drive failure. Always power the
system OFF before moving cabinets.
