Chassis Fan Trays

The OmniSwitch 10K chassis houses two fan trays each with independently-operating fans. The fan trays
are the main temperature control components for the switch, providing cooling airflow for all
chassis components. This airflow is a crucial factor in the switch's overall operability. Refer to
Recommendations" on page 2-7
Important. Fan trays are required components. Never attempt to operate the switch without fan
trays installed.

Number of fans per tray
Note. When two fan trays are installed in the chassis, fans run at variable speeds based on detected
changes in ambient room temperature and chassis temperature (caused by normal switch operations).
However, if only one fan tray is installed in the chassis, all fans run at maximum speed. Fans may also run
at higher speeds after a reboot but will adjust as necessary after approximately 5 minutes.
