Installation Requirements and Guidelines
This chapter describes site guidelines that must be met before installing an
Enterasys NAC Controller into a rack or cabinet, Enterasys NAC Controller configuration
guidelines, and operating specifications for the Enterasys NAC Controller.
Site Guidelines
The following guidelines must be observed when a site is selected for the
Enterasys NAC Controller. If the guidelines are not followed, unsatisfactory network performance
may result.
•
To ensure proper ventilation and prevent overheating of the chassis in either the rackmounted
or standalone configuration, there must be 5.1 centimeters (2 inches) of clearance on either
side and in the rear of the unit.
•
To install the Enterasys NAC Controller as a freestanding unit on a shelf, the shelf must be
able to support 13.6 kilograms (30 pounds) of static weight.
•
To install the Enterasys NAC Controller as a rackmounted unit, care must be taken to ensure
that the rack used will support the unit and that the rack remains stable.
•
The power supplies for the Enterasys NAC Controller require two three‐pronged power
receptacles capable of delivering the current and voltage specified in “
page A‐2. Two ac outlets on independently fused circuits are required for each power supply,
and must be located less than 2 meters (6 feet) from the site. The power cord used and type of
outlet is dependent on the country. In the United States, two power cords with NEMA 5‐15P
plugs are provided with each power supply.

Ambient temperature at the installation site must be maintained between 5° and 40°C
(41° to 104°F). Temperature changes must be maintained within 10°C (18°F) per hour.
