Space Requirements

If you use an enclosed rack for an ERX14xx model, ensure that there is a minimum
of 3 inches of clearance between the inner side wall and the router. This clearance
space ensures adequate air flow.

Proper Rack Installation

To confirm proper equipment rack installation, verify the following:
CAUTION: To maintain airflow requirements, a plenum must be installed above
ERX14xx models before any other piece of equipment is installed above the router.
A fully loaded rack with three ERX14xx 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.
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.
