Juniper SRX4600

Action
•
Monitor the status of the fan modules. All the fan modules work in unison to cool the services gateway.
If one fan module fails, the redundant fan module acts as a backup. A major alarm is triggered when a
fan fails, and a minor alarm and major alarm is triggered when a fan module is removed. We recommend
that you replace the fan module immediately to maintain proper cooling.
•
To display the status of the cooling system, issue the show chassis environment command. The output
shown below is an example.
