Figure 11: E120 Router, Rear View
Rack-Mounted Installation
We recommend that you use a standard EIA distribution rack. See "Equipment Rack
Requirements" on page 99 for rack information.
Installation Guidelines
Before installing the systems in a rack, consider the following guidelines:
CAUTION: To maintain airflow requirements, a plenum must be installed above the
E320 router before any piece of equipment (other than an E320 router) is installed
above the router. This plenum is available from Juniper Networks. Plenums are not
required when E320 routers are installed above one another because the router has
a built-in plenum at the bottom. See "Installation Guidelines and Requirements" on
page 97 and Figure 34 on page 101.
NOTE: An optional mounting kit is available for mid-chassis mounting. Contact your
Juniper Networks sales representative for more information.
You can install up to three E320 Broadband Services Routers or six E120
Broadband Services Routers in a single 7-ft. (2.1-m) rack. Installing multiple
systems in a single rack enables you to maximize your available space.
Install heavier systems, such as an E320 router, on the bottom of the rack. Mount
lighter systems higher in the rack.
