We currently have a few hundred force 300-25 sms deployed. Within the last few months, we have had many calls for service with the SM being offline. We discover that they have been factory reset. The temps have been cold with only a few weeks below 0 degrees F. The average night temp has been 10-20 degrees with day temps 20-30. They are all on the same firmware and both new and old SMs. We have also disabled “reset on power sequence” but it still occurs. What could be the cause of this and has anyone else experienced this?
I don’t know what it is in your case - but I doubt it’s due to low radio temps. We have 100’s of Force 300 in the field, and at temps of -50F and windchill of -75F we have zero ePMP temp related issues.
By any chance did you download some tech support file right after the reset? Did you open a support ticket?
Temperature is not an issue usually. Do you use CnMaestro? Cloud or on premises? Maybe some other loggining system that can give us a clue.
It sounds like major issue so I strongly suggest to open a support ticket, add tech support files and provide as much info about your network as possible.
We use Maestro. I’ve got on SM that does it pretty frequently. We always assumed it was power issues at that location, so we added a UPS. I will have to look back and grab those logs and details and I will open a ticket once that’s done
Ok. And PM me please ticket number right after!
Force 300-25 Headaches
we have seen many self reset issues that are related to power, one of the most common is failure to secure the ethernet cable to the radio so that wind and other things can not easily disconnect the cable or shake it hard enough to cause intermittent power resets (too many can cause radio to reset to factory),
Other common issues are mains power fluctuations, bad/poor cable crimp/tool worn out, CCA cable!
There is always a chance that it is faulty hardware but that is not as common in the last two revisions as it was.
