When Operating a Computer
When operating a computer, observe the following operating guidelines:
J
To help prevent electric shock, plug computer power cables into
properly grounded power sources. Use cables equipped with
three-prong plugs to ensure proper grounding. Do not use adapter
plugs or remove the grounding prong from the cable.
J
Be sure nothing rests on chassis cables and that cables are not located
where they can be stepped on or tripped over.
J
Keep objects out of chassis openings. This can cause fire or electric
shock by shorting out interior components.
J
Keep chassis away from radiators and heat sources. Do not block
cooling vents or place chassis in a closed-in wall unit.
J
To help protect chassis from sudden, transient increases and decreases
in electrical power, use a surge suppressor, line conditioner, or
uninterruptible power supply (UPS).
J
Consideration should be given to the connection of the equipment to the
supply circuit and the effect that circuit overloading might have on
overcurrent protection and supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this
concern.
J
The ambient temperature within the rack may be greater than room
ambient temperature. Installation should be such that the amount of
air flow required for safe operation is not compromised. Consideration
should be given to the maximum rated ambient temperature.
