Since we wanted to receive alarms from Junos Space / Network Director about tempretures on EX switches , its possible . But if you want to receive temp. alarms once switch reaches specific temp. , then it need to be confgured on the EX .
Note: Change of Temperature thresholds on EX switch is not recommended by JTAC.
Tested by me on EX switch 3300 , JunOS: 12.3R9
This is hidden command , so type "set chassis temperature-threshold ?" at once
