The output is of an EX9208 switch. The output is similar for all EX9200 switches.
To check the status of a specific Switch Fabric, issue the show chassis environment cb
command and include the slot number of the SF. The output is similar to the following:
user@switch> show chassis environment cb 0

Maintaining the Fan Tray in EX9200 Switches
Purpose For optimum cooling, verify the condition of the fans.
Action Monitor the status of the fans. A fan tray contains multiple fans that work in unison to
cool the switch components. If one fan fails, the host subsystem adjusts the speed of
•
the remaining fans to maintain proper cooling. A major alarm is triggered when a fan
fails and a minor alarm and a major alarm are 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@switch> show chassis environment
