ZS4-4 Cooling Subsystem
The ZS4-4 internal components are cooled by air that is pulled in through the front of the
controller and exhausted out the back of the controller. Cooling occurs in two areas of the
chassis: the power supply area and the motherboard area.
The following figure shows the cooling zones and the approximate location of the temperature
sensors. The accompanying legend table provides sensor NAC names and sensor motherboard
designations.
