PA-220 Thermal Shutdown

AdamRayner — Tue, 20 Jul 2021 10:42:21 GMT

Morning All,

Here in the UK, we are in the midst of a heatwave and we have had 2 PA-220's shutdown for heat issues.

I can't find anywhere at what temperature the Palo shutdown due to temps? I thought it was the MAX Chasis temp, however, we have another Palo that's passed the MAX of 60c and not shutdown.

Has anyone got any info or experience?

Thanks.

Hi @AdamRayner

Do you have other PA-220 which passed 60°C or other paloalto firewalls?

When you enter the cli command "show system environmentals" you see the current values and also the min and max values for different environmental sensors. For example on a PA-220 here it looks like the following:

Thanks for the reply.

This is one that's just gone high.

----Thermal----
Slot Description Alarm Degrees C Min C Max C
S1 Temperature @ U48 True 60.50 0.00 60.00
S1 Temperature @ U49 True 60.50 0.00 60.00
S1 Temperature @ Cavium Core False 62.77 0.00 80.00

I just wonder when they actually shut down.
