Juniper EX3200 Hardware Guide

Figure 15: Airflow Through the EX3200 Switch Chassis
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.
