ERX 11.1.x Hardware Guide
CAUTION: To prevent electrostatic damage to the system and its components, make
sure persons handling the router wear an antistatic device.
Connectors are located on the I/O modules and the power input module. These
modules are installed from the rear of the router. (See Figure 14 on page 26.) See
"Cabling ERX Routers" on page 47 for cabling installation procedures.

Rack-Mounted Installation

We recommend that you use a standard EIA distribution rack. See "Equipment Rack
Requirements" on page 121 for detailed rack information.

Installation Guidelines

Before installing the systems in a rack, consider the following guidelines and refer
to Figure 15 on page 27:
CAUTION: If you install an ERX7xx model or ERX310 router directly above an
ERX14xx model in the same rack, you must install a plenum between the ERX7xx
model or ERX310 router and the ERX14xx model so that the air can circulate between
the systems. (See Figure 53 on page 124.) This plenum is available from Juniper
Networks.

Rack-Mounted Installation
You can install up to 3 ERX14xx models, 6 ERX7xx models, or 14 ERX310 routers
in a single 7-ft. (2.1 m) rack.
Installing multiple systems in a single rack enables you to maximize your available
space.
You can install an ERX14xx model, an ERX7xx model, and an ERX310 router
together in the same rack. (See Figure 15 on page 27.)
