Extreme Networks Consolidated Hardware Guide 2-13
Meeting Site Requirements
— Position the earth ground as close to the equipment rack as possible to maintain
the shortest wiring distance possible.
— Properly test the quality of the earth ground.
Note: Because building codes vary world-wide, Extreme Networks strongly
recommends that you consult an electrical contractor to ensure proper
equipment grounding is in place for your specific installation.
• Ground DC power supplies to earth ground by using the grounding terminals
provided.
Space Requirements for the Rack
Provide enough space in front of and behind the switch so that you can service it easily.
Allow a minimum of 4 feet (121.92 cm) in front of the rack and 2 feet (60.96 cm) behind
the rack. When using a relay rack, provide a minimum of 2 feet (60.96 cm) of space
behind the mounted equipment. Extra room on each side is optional.
Note: Install your equipment rack near an easily accessible power outlet. You
should power down your equipment only by removing the power cord from the
power source.
Securing the Rack
The rack should be attached to the wiring closet floor with 3/8 inch (9.5 mm) lag screws
or equivalent hardware. The floor under the rack should be level within 3/16 inch
