Figure 14: Airflow Through the J-EX4200 Switch Chassis
The fan tray used in a J-EX4200 switch comes with load-sharing redundancy that can
tolerate a single fan failure at room temperature (below 45° C/113° F) to still provide
sufficient cooling.
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

option in the Status menu in the LCD panel.
