WARNING: Two people are required to lift an E Series router.
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.

We recommend that you use a standard EIA distribution rack. See "Equipment Rack
Requirements" on page 121 for detailed rack information.
Before installing the systems in a rack, consider the following guidelines and refer to
Figure 15 on page 27:
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.)
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.
