Equipment Rack Requirements
When allocating equipment rack space, consider the following:
- Type of equipment racks recommended for the system
- Number of equipment racks required to hold your current system
- Future expansion
Make sure that your distribution rack meets basic mechanical and space
requirements and complies with conventional standards. In the United States,
use the EIA-310-D Cabinets, Racks, Panels, and Associated Equipment, September
Follow these mechanical requirements for your rack:
- Select from the following rack options:
- Two-post rack—A freestanding enclosed cabinet with two mounting
posts in the front
- Telco-type rack—Two adjacent mounting posts that you must
secure to the floor or an overhead structure
- Four-post rack—A freestanding open rack, either open or
- The rack must have at least two mounting posts.
- The distance between the mounting holes in the two posts must
be 18.31 inches ±.063 inch, as specified in EIA-310-D.
- An optional mounting kit is available for midchassis mounting.

If you use an enclosed rack for the system, ensure that there is a minimum
of 3 inches of clearance between the inner side wall and the system. This
clearance space ensures adequate air flow.

To confirm proper equipment rack installation, verify the following:
- Racks are installed and electrically grounded according to manufacturer
- Equipment racks are anchored to the floor and, when possible,
anchored to the ceiling as well.
- Equipment rack installations comply with applicable local, state,
and national codes.
