Installing the ERX System

Rack-Mounted Installation

Figure 2-5 ERX-700 series rear view
We recommend that you use a standard EIA distribution rack. Refer to
Rack Requirements in
rack information. Before installing the systems in the rack, consider the
following guidelines:
• You can install up to three ERX-1400 series systems in a single 84-inch
rack.
Installing multiple systems in a single rack allows you to maximize
your available space. An ERX-1400 series system has a plenum that
allows air to circulate between systems.
• You can install an ERX-1400 series system and an ERX-700 series
system together in the same rack.
If you install an ERX-700 series system above an ERX-1400 series
system in the same rack, you must install a plenum between the
ERX-700 series system and the ERX-1400 series system so that the air
can circulate between the systems. See
available from Juniper Networks.
If you install an ERX-1400 series system above an ERX-700 series
system, there is no need to install a plenum between the units because
the ERX-1400 series system has one at its base.
