7.

For each SCSI peripheral device connected to the port, if the device is:

−

The last or only device on the SCSI chain, install or enable SCSI termination

−

Not the last or only device on the SCSI chain, disable or remove SCSI termination

8.

Ensure that the power switch on each peripheral device is in the off position; then connect the

power cord from each peripheral device to an AC power outlet.

9.

Turn on power to all connected SCSI peripheral devices and then start the system.

10.

If necessary, install software drivers and configure the peripheral devices according to the

vendor’s instructions.

See Chapter 8, “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 connect the system to AC power.

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.
