Installation and safety considerations 2

•Allow the status LEDs to be clearly visible.

•Allow for twisted-pair cable to be always 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 feet) of each device, and is powered from an independent circuit breaker. As with any equipment, a filter or surge suppressor is recommended.

•Some combinations of intake and exhaust airflows may not be compatible with your environment. Consult your fan and power supply module FRU kit to determine the correct configuration.

•For a 4-post rail mount configuration, order the appropriate mounting kit and refer to the kit documentation.

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:

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.
