Installation and safety considerations
The site should meet the following requirements:
• Maintain the operating environment as specified in “Environmental considerations” on
page 10.
• The ICX 7750 should be installed with its top/bottom covers parallel to the floor. The ICX 7750
should not be installed upside down.
• Allow a minimum of 3 in. of space between the front and the back of the device and walls or
other obstructions for proper airflow.
• Allow at least 3 in. of space at the front and back of the device for the twisted-pair, fiber-optic,
and power cabling.
• Allow access 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 to any port, be sure to discharge any static charge stored on the cable by
touching the electrical contacts to ground surface.
