Your distribution rack should meet some basic mechanical and space requirements. Your rack should comply with conventional standards. In the U.S., use EIA Standard RS-310-C: Racks, Panels, and Associated Equipment.
Follow these mechanical requirements for your rack:
- 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
- Do not use an enclosed rack for the ERX-700 series. It does not provide adequate ventilation.
- A fully loaded rack with three ERX-1400 series systems must structurally support 300 pounds (136 kilograms).
- The system fits in a 19-inch rack. You can install a system in a 23-inch rack if you use the 23-inch ears available from Juniper Networks. Contact your Juniper Networks sales representative for more information.
If you use an enclosed rack for an ERX-1400 series system, ensure that there is a minimum of 3 inches of clearance between the inner side wall and the system. This clearance space will allow adequate air flow.
