Fan Tray Description
The frontal Fan Tray unit is a front-to-rear air-forced cooling system with a replaceable air filter. The air is sucked in from the front panel and extracted out the rear panel, as illustrated below:
Airflow Direction through Chassis
When installing the chassis, make sure that there is sufficient front and rear clearance for proper airflow into and out of the chassis.

Air Filter and Cover (within Fan Tray Cover)
For operating status of the Fan Tray module, check the FAN LED on the front panel, as described in FAN LED.
During system operation, the inner ambient temperature is continuously monitored. Upon excessive temperature conditions, an SNMP Temperature Alarm is generated (acBoardTemperatureAlarm). Upon a speed degradation or full stop of any fan, an SNMP Fan Alarm (acFanTrayAlarm) is generated.
The Fan Tray module is hot-swappable, allowing you to replace it even when the device is powered on. The Fan Tray module and air filter are available as field-replaceable units (FRU). For replacing the Fan Tray module, see Replacing the Fan Tray Module. For replacing the air filter, see Replacing the Air Filter. (The Fan Tray cover is not replaceable.)
