Part I
Basic Workstation Hardware
Getting Started
This chapter tells you
What site requirements must be met so your hardware can
operate efficiently and safely
How to check the voltage requirements of the devices that
make up your workstation
What parts make up the basic DECstation 5000 Model 200
workstation
1
Getting Started 1–1
Workstation Site Requirements
For your DECstation 5000 Model 200 workstation to function
efficiently, your work environment must meet the requirements
listed here.
Caution: Failure to meet these requirements can damage equipment.
Temperature
Keep the temperature around the workstation between 50
and 104 degrees Fahrenheit (10 and 40 degrees Celsius).
– Set up your workstation away from heaters,
photocopiers, and other sources of heat.
– Protect your workstation from sunlight.
Allow air to flow freely around your workstation to keep
heat from building up and damaging your equipment.
– Leave 4 inches (10 cm) of space between system unit
vents and other objects.
– Leave 3 inches (8 cm) of space between monitor vents
and other objects.
Humidity
Keep relative humidity within the range of 10 to 80 percent.
Cleanliness
Keep your work area as dust-free as possible.
1–2 Getting Started
Interference
Set up your workstation at least 30 inches (90 cm) away
from other terminals or monitors and from other sources
of electrical interference, such as printers or electric pencil
sharpeners.
Limit exposure to static electricity and magnetized objects
by setting up your workstation away from busy corridors
and other high-traffic areas and away from filing cabinets
and steel beams in walls.
Power
Provide a 15-ampere branch circuit for the exclusive use of
your workstation.
Be sure your electrical circuit is properly grounded and free
from electrical noise.
Be sure the voltage for workstation devices matches that of
your power source.
Supplies
Store supplies, such as tape cartridges, within the same
temperature and humidity limits as those for your
workstation.
Getting Started 1–3
Workstation Voltage Requirements
The voltage for many devices, including most monitors, must
match that of your power source. Your power source is either
110/120 or 220/240 volts. 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.

The System Unit
The system unit is designed to sit flat on a level surface with
the monitor placed on top of or next to it.
Caution: Standing the system unit on its side blocks vents and can
damage the unit.
Connectors, Controls, and Indicator Lights on the System Unit
The back of the system unit contains the connectors, controls,
and indicator lights pictured in Figure 2-1 and described in
Table 2-1. Icons that appear on the system unit are pictured in
