Rack Specifications and Recommendations

Racks should conform to conventional standards. In the United States, use EIA Standard RS-310C:
Racks, Panels, and Associated Equipment. In countries other than the United States, use IEC Standard
297. In addition, verify that your rack meets the basic mechanical, space, and earthquake requirements
that are described in this section.

Mechanical Recommendations for the Rack

Use equipment racks that meet the following mechanical recommendations:

Use an open style, 19-inch rack to facilitate easy maintenance and to provide proper ventilation.

Use a rack made of steel or aluminum.

The rack should use the universal mounting rail hole pattern that is identified in IEC Standard 297.

The rack should have designated earth grounding connections (typically on the base).

The rack must meet earthquake safety requirements equal to that of the installed chassis.

The mounting holes should be flush with the rails to accommodate the chassis.

The rack should support approximately 600 pounds (272 kilograms).

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.

All Extreme Networks switches are designed with mounting brackets that provide solid metal-to-metal
connection to the rack. If you do not use equipment racks, you can attach wiring terminals directly to
the mounting brackets for appropriate grounding. Extreme Networks switches have grounding
terminals that are mounted on the back of the chassis.
