Which of the following Cisco TelePresence System models is least likely to require additional cooling?

A.
CTS 500

B.
CTS 1000

C.
CTS 3000

D.
CTS 3200

Explanation:
Of the choices provided, the Cisco TelePresence System (CTS) 500 is least likely to require additional cooling.
The heat generated by a CTS 500, one person with a laptop, and adequate lighting is estimated at 1,700 British
Thermal Units (BTUs) per hour, which should not change the room’s temperature significantly. A BTU is a
measurement of heat energy. Heating, ventilation, and air conditioning (HVAC) systems are typically rated in
BTUs per hour. To estimate the base cooling needs for a room or a building, multiply the square footage by 25.
The CTS 1000, CTS 3000, and CTS 3200 are more likely to require additional cooling. The following table
indicates the amount of heat that is generated in a typical Cisco TelePresence room:
