Mechanical Requirements for the Rack

Verify that your racks comply with the standards and requirements in your cabling system plan and conform to these conventional standards:

■In the United States, comply with EIA Standard RS-310C: Racks, Panels, and Associated Equipment.

Distribution Rack Requirements

B-3

■In countries other than the United States, comply with IEC Standard 297: Dimensions of Panels and Racks.

In addition, 3Com recommends that your distribution racks meet these requirements:

■Use an open style, 19-inch rack. The rack styles shown in Figure B-2 facilitate easy maintenance and provide excellent ventilation.

■Use a rack that has the universal mounting rail hole pattern identified in IEC Standard 297. See Figure 2-3 for a description of the universal mounting hole pattern.

■Use a rack that is made of steel.

■Install equipment in the lower half of the distribution rack to avoid making it top heavy.

■Use a rack that supports approximately 272 kg (600 lb)

■Use a rack that has adequate electrical grounding, for instance, with a distribution rack grounding kit.

■Verify that the floor under the rack is level within 5 mm (3/16 in.). Use a floor-leveling cement compound or bolt the racks to the floor.

■Attach the rack to the wiring closet floor with

9.5 mm (3/8 in.) lag screws or equivalent hardware.

■Brace open distribution racks if the channel thickness is less than 6.4 mm ( 1/4 in.).
