• Choose 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.
• Make sure to connect DC power supplies to a grounded return.
• 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.
• Keep power and interface cables clear of foot traffic. Route cables inside walls, under the
floor, through the ceiling or in protective channels or raceways.
• Route interface cables away from motors and other sources of magnetic or radio frequency
interference.
• Stay within specified cable length limitations.
• Leave enough space in front and back of the equipment to allow access for servicing.
When installing Avocent equipment in a rack or cabinet, observe the following precautions:
• Ensure that the floor’s surface is level.
• Load equipment starting at the bottom first and fill the rack or cabinet from the bottom to
the top.
• Exercise caution to ensure that the rack or cabinet does not tip during installation and use
an anti-tilt bar.
When using a desk or table, observe the following precautions:
• Choose a desk or table sturdy enough to hold the equipment.
