The chassis has a front-to-rear airflow. Four internal fans draw cooling air in through the front of the chassis
and across internal components to maintain an acceptable operating temperature. The fans are located at the
rear of the chassis. The fans are numbered from 0 to 3, right to left.
Caution
The power supplies used in Cisco Catalyst 9800-80 Wireless Controllers are different and they should not be
mixed or swapped. The size and structural dimensions are the same, therefore they both look alike. It would
be hazardous, if you accidentally inserted the wrong power supply into the PEM slot.
