The MX48 uses 3 DC fans all located conveniently in one modular fan tray. The tray is designed to move air horizontally through the enclosure. This hot-swappable fan tray allows for easy replacement of the module (in case of failure) without interrupting the system functionality. Any 2 DC fans will adequately cool either system.

The fan tray is also equipped with an Annunciator Port for the use of alarms. The system alarms can be configured to trigger an external control system or generate email notifications.
