Safety Guidelines

Copyright © 2010, Juniper Networks, Inc.
If you install an ERX14xx model above an ERX7xx model or ERX310 router, there is no
need to install a plenum between the units because the ERX7xx models and ERX310
routers vent air out the side of the chassis.
Install heavier systems, such as an ERX14xx model, on the bottom of the rack. Mount
lighter systems, such as the ERX310 router, higher in the rack.

Observe the following safety guidelines when mounting the router in a rack.
WARNING: Install equipment in the rack from the bottom upward. This helps
to maintain the stability of the rack and reduces the chance of the rack tipping
over.
WARNING: Three people are required to install the router in a rack: two to
lift the system into position and one to screw it to the rack.
