Ex4300 temp so high

‎09-19-2019 09:00 AM

We are facing weird issue the temp of the switch is very high

Temp FPC 0 CPU OK 73 degrees C / 163 degrees F
FPC 0 NW-PFE OK 40 degrees C / 104 degrees F
FPC 0 SE-PFE OK 42 degrees C / 107 degrees F
FPC 0 PHY-2/3 OK 39 degrees C / 102 degrees F
FPC 0 MGMT PHY OK 41 degrees C / 105 degrees F
FPC 0 PHY-4/5 OK 39 degrees C / 102 degrees F
Fans FPC 0 Fan 0 OK Spinning at normal speed
FPC 0 Fan 0 Airflow OK Airflow Out (AFO)
FPC 0 Fan 1 OK Spinning at normal speed
FPC 0 Fan 1 Airflow OK Airflow Out (AFO)

Can anyone suggest what is wrong?  We checked the temp in Datacenter is not high.

What version of SW are you on?  There was a PR1446363 for EX4600 (which also affected EX4300 I believe) where false alarms were being triggered.  See - https://kb.juniper.net/InfoCenter/index?page=content&id=TSB17632&actp=METADATA

 

As for improper reporting of temp, I have never heard of this.  You might want to check the fans for excessive dust build-up?

 

Good luck.

Hello,

 

The temperature seen on EX4300 device's output is high.

 

If the data center temperature is fine, please physically examine whether all the EX4300's fans are spinning. If there is any issue with FAN, then there would be rise in temperature.

 

Check this PR --> https://prsearch.juniper.net/InfoCenter/index?page=prcontent&id=PR1419300

Following the steps from Troubleshooting Temperature Alarms in EX Series Switches, could you please share outputs of "show chassis environment" and "show chassis temperature-thresholds" commands?

 

Best regards,
