5.5 Powering Off the System
To power off the system:
1. Back up system files as necessary.
See Solaris Handbook for SMCC Peripherals, part number 802-7675.
Caution –
Exit from the operating system before turning off system power. Failure
to do so may result in data loss.
2. Press the system standby switch (
FIGURE 5-1
), or press the Sun Type-5 keyboard
Standby key (
FIGURE 5-2
) or the Sun I/O Type-6 keyboard Power key (
FIGURE 5-3
).
Note –
For the system to gracefully shut down by the standby switch or the Sun
Type-5/6 keyboard Standby/Power key, UNIX must be operating. If the system is in
POST, the standby switch and the Standby/Power key are inoperative.
Caution –
Pressing the standby switch or pressing the Sun Type-5/6 keyboard
Standby/Power key does not remove all power from the system; a trickle voltage
remains in the power supply. To remove all power from the system, set the power
switch on the back panel to the off position.
