Fan Tray CAUTION: The W-7200 controller is equipped with a field-replaceable, hot-swappable fan tray. Each fan tray features four individual fans that pull air through the chassis from the front through to the rear. Each fan tray can tolerate the failure of a single fan while maintaining a safe operating temperature for the controller CAUTION: The W-7200 controller is not compatible with fan trays from other Dell hardware platforms. Hot Swapping Hot swapping allows you to replace a failed fan tray, making it unnecessary to shut down the W-7200 controller during the replacement procedure.
