C9300L-48P-4G: Switch reloading due to thermal temperature violation

[ReneIversen]

Hi 

We are experiencing that a switch is reloading due to error: Hotspot temperature is above maximum limit and will be immediately shut down.
But the temperatures on the switch are normal.

First we see multiple: 2042: 002048: Mar 4 19:27:52.273: Switch 1 R0/0: cmand: Hotspot temperature has exceeded RED threshold. Switch will shutdown soon.

Then we get: 2046: 002052: Mar 4 19:28:12.454: Switch 1: Hotspot temperature is above maximum limit and will be immediately shut down.

After this the switch will reload.

We have Tried with different Software versions, 17.3.5, 17.12.4 and 17.15.2.

Has anyone had same issue, and found a software version that is working without the bug?
I have found bug: CSCwf47107   that looks to be same problem, but there is no resolution.

Thanks 

René

Organize for the switch to be RMAed. 

The internal temperature sensor is faulty.  

Look at the output above:  Sensor detects the temperature to be -171C and the next day is 143C.

Thank you Leo, I have created RMA for this switch.
