2.4.6 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 Figure 6 for an illustration of the fan tray.
The fans are controlled by the system software, and their speed is set according to
the environmental temperature surrounding the switch. Allow at least 3 in. (7.62 cm)
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.
Figure 6 Fan Tray
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
replace it when accumulated dust is present.
