Maintaining the Fan Tray on the SRX3600 Services Gateway
The fan tray contains multiple fans that work in unison to cool the services gateway components. If one
fan fails, the Routing Engine adjusts the speed of the remaining fans to maintain proper cooling. A red
alarm is triggered when a fan fails, and a yellow alarm and red alarm is triggered when a fan tray is removed.
To display the status of the cooling system, issue the show chassis environment command. The output is
similar to the following:
user@host> show chassis environment
