XGS1250-12 - all 10G ports are not working after short power outage

stoicavictormarius · January 2025

Seems that with my XGS1250-12 I just faced the same issue as described here https://community.zyxel.com/en/discussion/14655/xgs1250-12-port-9-and-10-dont-work-after-power-down. More precisely last night there was a short power outage and in the morning I found that all 10G ports were not usable anymore, although just one was used when the power outage happened.
On the other hand, all 1G ports are working just fine and I can still access and manage the switch via the web interface.
The switch was bought on 12.07.2022, thus it is out of the 2y warranty.
Is this already a known hardware issue? Can I still raise a RMA request?

Hi @stoicavictormarius ,

Could you help to loop the 10G ports were not usable to another port in order to confirm if the port can be up or not, if it doesn't works then please use this link to directly contact our local support for RMA. They'll confirm with you.

I have done the loop test with all the ports and also tested them with several laptops with working 1G or 10G ports. Unfortunately no connection is negotiated.
