Figure 11: E120 Router, Rear View
We recommend that you use a standard EIA distribution rack. See "Equipment Rack
Requirements" on page 97 for rack information.
Before installing the systems in a rack, consider the following guidelines:
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.
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 95 and Figure 34 on
page 99.
Install heavier systems, such as an E320 router, on the bottom of the rack. Mount lighter
systems higher in the rack.
NOTE: An optional mounting kit is available for mid-chassis mounting.
Contact your Juniper Networks sales representative for more information.
