Power Supplies for Use with Your

Switch

Each 7520 Series switch runs with two replaceable internal

power supply modules that provide all of the power needed

for the switch to operate. You can remove one power supply

module without interrupting the switch's operation. Supported

power supply configurations include two 800W AC power supply

modules, two 800W DC power supply modules, or one 800W AC

and one 800W DC power supply module. Power supply modules

have integrated cooling fans that operate independently of the

switch fans and are available with front-to-back or back-to-front

airflow. The direction of the airflow in both power supply modules

must be in the same direction and must also be in the same

direction of the airflow in the fan modules.
