Hi everyone,
lately I had a power outage at home and after the power was up again I had a problem with my CSS610-8G-2S+ switch.
The switch worked perfectly again after the event but a few days later I noticed, that the switch itself wasn't accessible anymore (no access to webGUI -> timeout; no output via SNMP anymore -> also timeout).
I'm absolutely sure that this behavior started with the power outage because I have a script running, that collects SNMP data from all my Mirkrotik devices. After the event it wasn't able to receive anymore data from the CSS610.
The only way to regain access to the config webGUI was to do a complete reset of the switch
This raises two questions:
* What could have caused this situation? I don't really understand, that the switch worked perfectly fine, but was not reachable
* How could I prevent this in the future? Even an UPS wouldn't have helped my me here because there is no way to explicitly power the switch down (and: this really shouldn't be necessary...)
Sidenote: My RouterOS devices didn't have any issues coming backup again.
Thanks
