USG310 Intermittent Red SYS light

TAPTech

We have at least 20 USG40 and USG60 devices at client locations that run great, and are very reliable.  We've recently taken over for a client that has a USG310 device.  One day the device locked up with a red SYS light and would not boot.  We received another USG310 device from Zyxel RMA.  After importing the config file, the device locked up again.  So, we rebuilt the config, which is not very complex.  The device was good for a week.

Today another red SYS light and the network was down.  We are running the latest firmware version 4.33.  Has anyone had similar problems with these units?  I am surprised because the USG60 units we usually use are always very stable.

Is it possibly something wrong with our config?

Hi @TAPTech  

The configuration will not cause red sys light.

For clarify the reason, can you dump the logs to terminal by console cable?

And share the log to me by private message.

Hi @TAPTech

As our discussion, the symptom is coming from fans stop working.

So it leads device temperature high and reboot itself.

Please contact with local representative for RMA.

Is it possible to monitor CPU temp via SNMP or syslog server?

Hi @TAPTech  

Currently temperature is unable monitor by SNMP.

I will add it as idea.

Thanks for your suggestion.
