EX3200 Cooling System
The cooling system in an EX3200 switch consists of a field-replaceable unit (FRU) fan tray with one fan (see Figure 1).
The fan tray is located at the rear of the chassis. See Figure 1
Airflow Direction in the EX3200 Switch Chassis
The fan tray located at the rear of the chassis provides side-to-rear chassis cooling. See Figure 2
Temperature sensors in the chassis monitor the temperature within the chassis. The system raises an alarm if the fan fails or if the temperature inside the chassis rises above permitted levels. If the temperature inside the chassis rises above the threshold, the system shuts down automatically and the temperature shutdown LED on the rear panel is lit. You can see the status of fans and the temperature from the Show Environment Status option in the Status menu in the LCD panel.
