Set up the system unit and monitor.

Warning: It takes two people to unpack the monitor, system unit, and

BA42 storage expansion box safely.

Cautions: Placing the system unit on its side blocks air vents and

causes the unit to overheat.
Placing the monitor near electromagnetic devices, such as printers or

electric pencil sharpeners, or near magnetized objects, such as filing
cabinets or steel beams in walls, can interfere with its performance.

Be sure the on/off switches on the system unit and monitor are
in the off position.

Press the 0 on the on/off switch on the system unit, the 19-inch
VRT19 color monitor, the 16-inch VR297 color monitor, and the
VR262 gray scale monitor. Press and release the on/off switch
on the 19-inch VR299 color monitor.

Press the 0 on
this type of switch.

Press and release this
type of switch.

Familiarize yourself with base system slots 5 and 6 and with
the three option slots on the back of the system unit.

The basic workstation comes with a SCSI connector in base
slot 5 and a ThinWire Ethernet connector in base slot 6 on the
system unit.

You can have option modules in option slots 0, 1, and 2.
Direct memory access priority for the option slots is as follows:

Slot 2—Highest priority. Use this slot to connect hardware

you want to access memory first.
Slot 1—Next highest priority.
Slot 0—Lowest priority.

Set up any expansion boxes.

You can connect up to seven SCSI devices to a SCSI connector
on the system unit so long as the amount of internal and
external cabling does not exceed 19 feet 8 inches in length.

Caution: Using more than 19 feet 8 inches (236 inches) of cable,

including cable inside expansion boxes, to connect devices to a given
SCSI connector on the system unit can make those devices unreliable.

When you stack your storage device expansion boxes, use the
following table to determine how much cable you will be using.

Cable Length

BA42 storage expansion box internal cable 30 inches
TK50Z tape drive internal cable 14 inches
RRD40 optical compact disc drive internal cable 6.5 inches
TLZ04 tape drive internal cable 38 inches
50-pin to 50-pin box-to-box external cable 18 inches
68-pin to 50-pin system-unit-to-expansion-box external

cable

74 inches

Be sure expansion box on/off switches are in the off
position.

Press the 0 on the on/off switch on the BA42 storage expansion
box, the TK50Z tape drive expansion box, and the RRD40
optical compact disc drive expansion box.

Press and release the on/off switch on the TLZ04 tape drive to
turn it on and off.

Check voltage requirements.

The voltage for many devices, including most monitors, must
match that of your power source. Where necessary, a yellow
voltage label that covers the power connector on your device
tells you the voltage requirements for that device.

Caution: Connecting a device to a power source that does not meet

the voltage requirements of that device can damage the device.

Then connect the T-connector to the ThinWire connector in base
slot 6 on the system unit.

Twist the ribbed portion of the T-connector from side to
side until you can push it into the system unit connector.
Then turn it to the right until it locks into place.

Attach any ThickWire loopback connectors.

Optional ThickWire Ethernet connectors can be present in any
of the option slots on the back of the system unit. Each must
have a loopback connector in place until the Ethernet cable is
connected to the system unit and the network.
