Description

i2c_check_temp_limits: PIC 1 temperature sensor qsfp has temperature 126 above fire temperature (FIRE_TEMP) threshold 70 

 

PIC <>:qsfp-<> temperature of 126 degrees C is above limit (85 degrees)

 

 

Customer questions were if there is anyway that the QSFP can be disabled instead of the whole PIC. 

 

We checked with development team if there is a built-in mechanism to disable the QSFP in question rather than the whole PIC – there is none yet. That said, we were able to find a PFE command that can be used to power off QSFP ‘ test qsfp <index> power <off/on>’. Theoretically it should take out QSFP in such a way that completely eliminates temperature load. One possible use is to automate it through script to run when high temperature is hit
