General safety precautions
Observe the following general safety precautions when setting up and using Avocent equipment.
Do not push objects through the openings in the equipment. Dangerous voltages may be present. Objects with conductive properties can cause fire, electric shock, or damage to the equipment.
Chose a location that avoids excessive heat, direct sunlight, dust, or chemical exposure, all of which can cause the product to fail. For example, do not place an Avocent product near a radiator or heat register. which can cause overheating.
Connect products that have dual power supplies to two separate power sources, for example, one commercial circuit and one uninterruptible power supply (UPS). The power sources must be independent of each other and must be controlled by separate circuit breakers.
For products that have AC power supplies, ensure that the voltage and frequency of the power source match the voltage and frequency on the label on the equipment.
Products with AC power supplies have grounding-type three-wire power cords. Make sure the power cords are plugged into single-phase power systems that have a neutral ground.
Do not use household extension power cords with Avocent equipment because household extension cords are not designed for use with computer systems and do not have overload protection.
Ensure that air flow is sufficient to prevent extreme operating temperatures. Provide a minimum space of 6 inches (15 cm) in front and back for adequate airflow.
