Providing Adequate Space for the Rack

Provide enough space in front of and behind the equipment, so that you can service it easily and so that airflow is not impeded.

We recommend providing a minimum of 122 cm (48 in) in front of the rack and 76 cm (30 in) behind the rack. When using a relay (two-post) rack, provide a minimum of 61 cm (24 in) of space behind the mounted equipment. Extra room on each side is optional.


The equipment does not have a switch for turning power on and off. For systems using an AC power supply, power to the switch is disconnected by removing the wall plug from the electrical outlet.

Be sure that cables and other equipment do not block the switch's air intake or outflow.
