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.
NOTE: Based on the optical fiber cables used, you may need to increase the
physical space provided for the chassis. The strain relief and bend radius
requirements of the optical fiber cables may exceed the specified depth of
the chassis and the cable-management bracket.
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 89 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 router. Otherwise, the router
might overheat.
See "System Specifications" on page 89, for a complete list of regulatory compliance
requirements, including safety, EMC, and telecommunications.
For your safety, before installing the system, review all safety warnings in this section.
WARNING: The recommended maximum ambient temperature is 40˚° C
(104° F). For safe operation take into consideration the internal temperature
within 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 can cause electric shock and serious
burns.
