Chassis Fan Tray
The OmniSwitch 6900 chassis houses a single fan tray with four independently-operating fan. The fans 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 “Airflow
Recommendations” on page 2-16 for more information.
Important. The fan tray is a required component. Never attempt to operate the switch without a fan
tray installed.
