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 configuration
- 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 1992 standard.
Mechanical Requirements
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 closed
- 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.
Contact your Juniper Networks sales representative for more information.
Space Requirements
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.
Proper Rack Installation
To confirm proper equipment rack installation, verify the following:
- Racks are installed and electrically grounded according
to manufacturer instructions.
- 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.
