Providing Adequate Space for the Rack
•
Position the earth ground as close to the equipment rack as possible to maintain the shortest wiring
distance possible.
•
Use a ground impedance tester or micro-ohm meter to test the quality of earth ground connection
at the chassis. This will ensure good grounding between the chassis, rack, and earth ground.
Note
Because building codes vary worldwide, Extreme Networks strongly recommends that you
consult an electrical contractor to ensure proper equipment grounding for your specific
installation.
Providing Adequate Space for the Rack
Provide enough space in front of and behind the switch so that you can service it easily.
Allow a minimum of 48 inches (122 cm) in front of the rack and 30 inches (76 cm) behind the rack.
When using a relay (two-post) rack, provide a minimum of 24 inches (61 cm) of space behind the
mounted equipment. Extra room on each side is optional.
Warning
Extreme Networks switches do not have a switch for turning power to the unit 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.
Depending on other conditions in the equipment room, it may be possible to install the switches closer
to each other; consult your Extreme Networks Customer Support representative for guidance.
Securing the Rack
The rack should be attached to the wiring closet floor with 9.5 mm (3/8 in) lag screws or equivalent
hardware. The floor under the rack should be level within 5 mm (3/16 in). Use a floor-leveling cement
compound if necessary or bolt the racks to the floor as shown.
