Environmental Requirements
It is important to remember that the cleaner the environment, the more efficiently the
computer performs. Treat your computer with respect. For example, do not place coffee
cups or soda cans on top of the main enclosure where they can spill. If spilled liquid
happens to reach the circuit boards inside the computer, it could cause computer failure.
In general, you should install your computer in an area where people do not eat, drink,
or smoke, since all of these activities can cause contamination problems. Try not to
place the computer in a high traffic area. This typically creates more dirt and dust which
can clog the air intakes of the computer chassis. This will cause cooling problems
because of the dirt accumulation. A side effect of a high traffic area is static electrical
discharge which can cause system resets. This can be avoided by installing the
computer in a better environment. For information on cleaning your computer and
taking care of its components, refer to Chapter 6, "Preventive Maintenance."
When you select a location for your computer, remember that it operates within certain
temperature and humidity ranges. Air circulation around the system is something that
should be considered. Do not put a computer in a closed closet where there is no
cooling. See the separate specification sheet for detailed requirements.
It is very important for the health of your computer that you do not obstruct its cooling
system. The computer takes air in from the front and bottom and exhausts air at the
rear. The mounting feet give it adequate ventilation space below. Allow at least six
inches at the rear of the unit for ventilation. Do not place the computer on a carpet
which can block the air intakes on the bottom of the system.
Static Electricity
Slight problems with the computer can often be traced to problems with static electricity
or improper grounding.
If you have problems on dry and windy days when humidity is low, static electricity could
be your problem.
If, however, your problems occur when equipment near the computer is turned on—for
example, if your computer stops functioning when someone uses the photocopier—
improper grounding could be your problem. We recommend a low impedance power
conditioner be used to filter out these power problems. Alpha Microsystems can provide
the approved power conditioner type. Ask your VAR for further details.
One of the greatest enemies of computers, terminals, and printers is static electricity.
The chief villain is climate: dry winds and dry seasons. You should also be aware that
both carpets and the plastic mats often used under desks are a prime source of static
electricity.
If possible, you should place your computer in an uncarpeted area. If you must place it
in a carpeted area where static electricity could be a problem, you should treat the area
with anti-static spray on a regular basis.
