handle for insertion and removal of the unit. Airflow enters from the front vents on the PSU and exits
to the rear vents of the switch. Airflow through the Extreme Networks 700/1200 W AC PSU AC is
independent from the airflow through the rest of the switch.
The AC input connection is located on the switch directly below each installed power supply.
