Installation Guidelines and Requirements

The distance betweenthe 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-310router. 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 m ore information.

Space Requirements

If you use an enclosed rack for an ERX-14xx model, ensurethat 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

Toconfirm proper equipme nt rackin stallation, verifyth e following:

Racks are installed and electrically grounded according to manufacturer

instructions.

Equipment racks are anchoredto the floor and, when possible, anchored to

the ceiling as well.

Equipment rack installations comply with applicable local, state,a nd national

codes.

CAUTION: Tomaintain airflow requirements, a plenum must be installed above

ERX-14xx models before any other piece of equipment is installed above the router.
