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.
Figure 7 Fan Tray
Figure 8 shows the airflow pattern for the W-7200 controller. The blue arrows show cool air being pulled into the
device and the red arrows show warm air being forced out by the fan tray module. When installing your W-7200
controller, ensure that you leave sufficient space around the device for proper airflow.
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.
