Installation guide

• Allow at least 3 in. of space at the front and back of the device for the twisted-pair, fiber-optic, and
power cabling.
• Be accessible for installing, cabling, and maintaining the devices.
• Allow the status LEDs to be clearly visible.
• Allow for twisted-pair cables to be routed away from power lines, fluorescent lighting fixtures, and
other sources of electrical interference, such as radios and transmitters.
• Allow for the unit to be connected to a separate grounded power outlet that provides 100 to 240 VAC,
50 to 60 Hz, is within 2 m (6.6 ft) of each device, and is powered from an independent circuit breaker.
As with any equipment, a filter or surge suppressor is recommended.
Cabinet considerations
For successful installation and operation of the switch in a cabinet, ensure the following cabinet
requirements are met:
• The cabinet must be a standard EIA cabinet.
• The equipment in the cabinet is grounded through a reliable branch circuit connection and maintains
ground at all times. Do not rely on a secondary connection to a branch circuit, such as a power strip.
• Airflow and temperature requirements are met on an ongoing basis, particularly if the switch is
installed in a closed or multicabinet assembly.
• The additional weight of the switch does not exceed the cabinet’s weight limits or unbalance the
cabinet in any way.
• The cabinet is secured to ensure stability in case of unexpected movement, such as an earthquake.
Recommendations for cable management
Cables can be organized and managed in a variety of ways; for example, use cable channels on the
sides of the cabinet or patch panels to reduce the potential for tangling the cables. The following list
provides some recommendations for cable management:
CAUTION
Before plugging a cable into to any port, be sure to discharge the voltage stored on the cable by
touching the electrical contacts to ground surface.
NOTE
You should not use tie wraps with optical cables because they are easily overtightened and can
damage the optic fibers. Velcro-like wraps are recommended.
• Plan for the rack space required for cable management before installing the switch.
• Leave at least 1 m (3.28 ft) of slack for each port cable. This provides room to remove and replace
the switch, allows for inadvertent movement of the rack, and helps prevent the cables from being
bent to less than the minimum bend radius.
• For easier maintenance, label the cables and record the devices to which they are connected.
• Keep LEDs visible by routing port cables and other cables away from the LEDs.
