Mechanical Requirements for the Rack

Racks should comply with the standards and
requirements mentioned in your cabling system
plan and should also conform to certain
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: Dimensions of Panels and Racks.
In addition, 3Com recommends that your
distribution rack meet these requirements:
Use an open style, 19-inch rack. The rack styles
shown in Figure C-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
page 2-3 for the 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 the rack
top-heavy.
