Rack-Mounted Installation
We recommend that you use a standard EIA distribution rack. See Equipment Rack Requirements for rack information.
Installation Guidelines
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 and Figure 34.
- 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. |
Preparing the Equipment Racks
Following your installation plan, use a tape measure and marking pen to measure and mark space on each equipment rack for each router component. For horizontal spacing follow Network Equipment Building System (NEBS) requirements. 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. If you choose not to install a plenum, be sure to include 2 U of space between the E320 router and the other component for proper exhaust. A plenum, however, is highly recommended.
Installing the Router
To complete the installation of the router in a rack, you need:
- A No. 2 Phillips screwdriver
- Eight 10-32 x 3/8 Phillips screws (provided with the router) for each router to be installed
![]() | Warning: Do not use the cable management bracket as a handle to lift the E320 router. |
To install the router in the rack:
- With one person standing on the left side of the router and another standing on the right side, lift the router into the rack.
- Position the router in its designated location in the equipment rack. Make sure the holes of the mounting brackets align evenly with the holes of the equipment rack on both sides.
- Starting at the bottom of the router, have the third person secure the router in the equipment rack by using the 10-32 x 3/8 Phillips screws.
- Connect the necessary cables. (See Cabling the Router for instructions on installing the cables.)
