Chapter 1: Product Overview 3

• 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.

• 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.

• 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.

• Keep CAT 5 cable as far away as possible from potential sources of EMI, such as electrical

cables, transformers and light fixtures. Do not tie cables to electrical conduits or lay cables on

electrical fixtures.
