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 the EIA-310-D.
Do not use an enclosed rack for ERX-7xx models or the ERX-310 router. It does not provide adequate ventilation.
A fully loaded rack with three ERX-14xx models must structurally support 300 pounds (136 kilograms).
Optional mounting kits are available for 19-inch and 23-inch rack mounting (mid-chassis and front-chassis mounting). Contact your Juniper Networks sales representative for more information.
