Cisco Systems IAD2430 用户手册

Enclosed racks must have adequate ventilation. An enclosed rack should never be overcrowded and 
should have louvers and a fan. 

If you install the chassis by using slide rails, check for blocked ventilation ports when the chassis is 
positioned in the rack or cabinet. Make sure that the ventilation ports of the Cisco IAD are not blocked. 

Baffles can help isolate exhaust air from intake air. Baffles also help draw cooling air through the 
cabinet. The best location for the baffles depends on the airflow patterns in the rack. You can test the 
airflow by experimenting with various equipment arrangements. 

If you install the Cisco IAD on a wall, there should be plenty of space on both sides for adequate airflow 
through the chassis.

If you place the unit on a desktop, do not stack other equipment or paper on the chassis. Allow plenty of 
space for air circulation (front to back). Inadequate ventilation can result in equipment overheating and 
damage.

Allow space at the back of the chassis for cable connections. Also consider the need to access the chassis 
for future upgrades, maintenance, and troubleshooting.

Chassis grounding is provided through the power cable, which uses a standard grounding plug. However, 
the chassis also requires a reliable earth ground, using the earth ground lug and hardware provided. For 
more information, see the 

A Cisco IAD2430 series IADs with AC power supply autoselects either 100- to 127-V or 200- to 240-V 
operation. The Cisco IADs with AC power supply include a 6-foot (1.8-meter) electrical power cord. (A 
label near the power cord indicates the correct voltage, frequency, current draw, and power dissipation.)

The Cisco IAD2435 IAD connects to a 60-W, 12-VDC power adapter with the following specifications:

Input voltage—85 to 264 VAC

Input frequency—47 to 63 Hz

Power output—60 W maximum

Output voltage—+12 VDC
