ERX 11.1.x Hardware Guide
Choose a location for the router that is dry, relatively dust free, well ventilated, and
air conditioned. If you install equipment in a rack, be sure that the floor is capable
of supporting the combined weight of the rack and the installed equipment. Place
the router in a location with sufficient access to power and network cables.
Like other network devices, the router generates a significant amount of heat. You
must provide a balanced environment so that the router performs properly and
safely. See "System Specifications" on page 109 for acceptable ranges of temperature
and humidity.
Be sure to allow enough space around the router for adequate ventilation. Inadequate
ventilation can cause the system to overheat.
CAUTION: Do not block the air vents on the routers. Otherwise, the router might
overheat.

Regulatory Compliances

See "System Specifications" on page 109, for a complete list of regulatory compliance
requirements, including safety, EMC, and telecommunications.

Safety Guidelines

For your safety, before installing the system, review all safety warnings in this section.
WARNING: The recommended maximum ambient temperature is 50° C (122° F).
For safe operation, take into consideration the internal temperature of the rack.
WARNING: Install equipment in the rack from the bottom upward. Doing this helps
maintain the stability of the rack and reduces the chance of the rack tipping over.
WARNING: Do not insert any metal object, such as a screwdriver, into an open slot
or the backplane. Doing so might cause electric shock and serious burns.
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.
WARNING: Connect the router or rack to ground (earth), and ensure that a reliable
grounding path is maintained in the rack.
