more detailed information about any procedure, refer to the
table of contents.
Table 1.

Conventions Used in This Guide

Convention

Use

Monospace type

Anything that appears on your monitor
screen is set in monospace, like this.

Getling Started

This chapter tells you
»

How to prepare your site so your workstation can operate
efficiently and safely

How to make sure your shipment contains everything you

need and what to do if something is missing or broken

. Review Site Requirements
For your DECstation 2100/3100 workstation to work efficiently,
your work environment must meet the requirements listed
here.
Caution:

Failure to meet these requirements can cause damage to

equipment.

Temperature
=

Keep the temperature around the workstation between 50°
and 104° Fahrenheit (10° and 40° Celsius).

—

Set up your workstation away from heaters,
photocopiers, and other sources of heat.

—

Protect your workstation from sunlight.

Getting Started

1-1

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 95 percent,
unless you have an RZ55 disk drive, in which case the
range should be 8 to 95 percent.

Cleanliness
»

Keep your work area as dust-free as possible.

Power

Set up your workstation at least 30 inches (90 cm) from
other terminals or monitors or other sources of electrical
interference.

Limit exposure to static electricity by setting up your

workstation away from busy corridors and other high-traffic
areas.

Provide a 6.5-ampere branch circuit for the exclusive use of
your workstation.

s«

Be sure your electrical circuit is properly grounded and free
from electrical noise.

Supplies
»

1-2

Store supplies, such as tape cartridges, at the same
temperature and humidity levels as your workstation.

Getling Started

Unpack and Check Your Equipment
As you unpack your shipment, check its contents against the
packing list. Save the packing materials in case you ever need
to store or ship your workstation.
Warning:

It takes two people to unpack the system unit and monitor

safely.

Your shipment should include all the items that appear in
Figure 1-1, plus your software and any options you have
ordered.
Note:

You do not need to use the power cord that comes with your

monitor. In the DECstation 2100/3100 workstation, the monitor
receives its power through the system unit, not from a wall outlet.
To provide power to the monitor, you use the power cable that comes

with your system unit.

Inform the delivery agent and your Digital sales representative
if any items are missing or damaged.
For a detailed list of items, with part numbers, available for
your workstation, see Appendix B.

Connect the Power Cable and Power Cord
With your shipment, you received a monitor—system unit power
cable that allows power to flow from the power source through
the system unit and to the monitor. You use this cable instead
of the power cord that came in your monitor carton.
Power cords for optional devices come with those devices. After
you have connected the system unit power cord and the power

cable, set up your optional devices and connect their power
cords according to the instructions that came with them.
The voltage for many devices, including most monitors, must
match that of your power source. It is either 110/120 or 220/240
volts. Where necessary, a yellow voltage label that covers the
power connector tells you what you have.

Starting and Testing the Workstation

Check the Results of the Power-Up Self-Test
After you turn on your system unit and monitor, your
workstation tests itself. This process takes about a minute.
The numbers that identify the subtests that make up the
self-test appear on your screen as your workstation runs them.

Because some subtests take longer than others, there are
times when nothing happens on your screen. For example, the
following display remains on your screen for several seconds:
KNO1

V6.71

7..6..5..4..

During testing, a display similar to the following gradually
appears on your screen:

KNO1

V6,71

7..6..5..4..3..2..1..0
