Protective Grounding for the Rack

Use a rack grounding kit and a ground conductor that is carried back to earth or to another suitable building ground.

Before you install an E4G series router in an equipment rack, clean the rack and mounting bracket surfaces and apply an antioxidant. When you secure an E4G series router to the rack, use thread-forming mounting screws that remove any paint or non-conductive coatings and establish metal-to-metal contact.

Extreme Networks equipment is designed with mounting brackets that provide solid metal-to-metal connection to the rack.

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.

At a minimum, follow these guidelines to ground equipment racks to the earth ground:

• CAD weld appropriate wire terminals to building I-beams or earth ground rods.
• Use a minimum 14 AWG stranded copper wire for grounding an E4G-200 router or a DC-powered E4G-400 router.

  An AC-powered E4G-400 router does not need separate chassis grounding.

• 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.
