If you want to boot the system from an external SCSI hard disk drive, ensure the SCSI controller to
which the boot drive is connected is installed lower in slot order than all other bootable SCSI
controllers and devices.
See Chapter 9, “Upgrading the System,” for additional details on installing external SCSI
peripheral devices.
Connecting to AC Power
CAUTION
The AC power cord for this unit is the service disconnect. To remove AC power from
the system, you must unplug the system power cord from its AC power outlet.
CAUTION
Ensure the AC power outlet to which the system’s power cord connects is close to
the system and is easily accessible
When you connect the system’s base unit to AC power, auxiliary power is applied to the system.
Auxiliary power ensures that system components power up quickly when needed. See Chapter 4,
“Operating the System,” for more information on controlling system power.
To connect the system to AC power:
1.
Make sure the AC voltage selection switch on the power supply (on the back of the base unit)
is set to the proper line voltage for your location.
−
If your location uses 90 to 135 volts, the number 115 must be visible.
−
If your location uses 180 to 264 volts, the number 230 must be visible.
WARNING
If you do not set the AC voltage selection switch on the power supply correctly,
equipment damage may occur when you turn on power to the system.
2.
Connect the system’s power cord to the AC power receptacle on the base unit.
3.
Connect the power cords from the monitor, base unit, and any external peripheral devices to
properly grounded, three-prong AC power outlets.
