Fan Tray

A hot-swappable fan tray on the right side of the front panel contains three fans that provide
cooling for the chassis. See
The fans are controlled by the system software, and their speed is set according to the
environmental temperature surrounding the switch. Allow at least three inches of clearance on the
side of the rack to ensure proper airflow intake cooling system. The fan trays must be in place
before the chassis is powered on.
The fan tray also contains an air filter. The filter tray must always be installed while the chassis is
powered up. The air filter prevents large particles, debris, and dust from entering and circulating
through the system. Inspect your air filter monthly and clean it when accumulated dust is present.
