2. Back up system files and data.
See the Solaris Handbook for SMCC Peripherals, part number 802-7675.
3. Halt the system.
Caution – Pressing the front panel power switch does not remove all power from
the system unit; a trickle voltage remains in the power supply. To remove all power
from the system unit, disconnect the AC power cord from the system unit.
4. Set the power on/standby switch to the stand-by (O) position (
FIGURE 6-1).
5. Verify the following:
a. Front panel LED is extinguished.
b. System fans are disabled.
Caution – When the power on/standby switch is in stand-by (0) and the AC power
cord remains connected to a power receptacle, AC voltage is present in the power
supply primary.
Caution – Disconnect the AC power cord from the AC receptacle prior to handling
the power supply. When servicing system components other than the power supply,
the AC power cord should remain connected to the AC receptacle.
6. Turn off the power to the monitor and any peripheral equipment.
