Specifications

Chapter 2 Product Overview
• Follow all cautions and instructions in the installation documentation or on any cautionary cards shipped with the
product.
• 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.
• Do not make mechanical or electrical modifications to the equipment.
• Do not block or cover openings on the equipment.
• 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 a BLACK BOX product near a radiator or heat register, which can cause
overheating.
• Ensure that the voltage and frequency of the power source match the voltage and frequency on the label on the
equipment.
• 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 BLACK BOX 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.
• 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 BLACK BOX 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.
• Place the equipment so that at least 50% of the equipment is inside the table or desk’s leg support area to avoid
tipping of the table or desk.
Cabling installation, maintenance and safety tips
The following is a list of important safety considerations that should be reviewed prior to installing or maintaining your
cables:
• Maintain the twists of the pairs all the way to the point of termination, or no more that one-half inch untwisted. Do not
cut off more than one inch of jacket while terminating.
• If bending the cable is necessary, make it gradual with no bend sharper than a one inch radius. Allowing the cable to
be sharply bent or kinked can permanently damage the cable’s interior.
• Dress the cables neatly with cable ties, using low to moderate pressure. Do not over tighten ties.
• Cross-connect cables where necessary, using rated punch blocks, patch panels and components. Do not splice or
bridge cable at any point.
