# Environmental Requirements

See System Specifications for complete environmental specifications.

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 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.
