Netgear XS508 and GS110MX causing power outage

Hello everyone,

There has been some progress on this topic so I thought il update. Unfortunately still not solved.

I think this problem is related to what schumaku mentioned, and is caused by electrical wiring problems of some sort (which I am very unfamiliar with). I have been able to find more resources online by counterintuitively searching for the topic in my native language rather than in English. Which has yielded a lot more information. It seems that there are substantial differences on how electricity is handled in a household depending on country.

I have done some additional testing and if I take both switches out of the server rack and connect them to one of the power sources that is in the same room as one of the devices that cause a current circuit breaker outage I can attach all devices except for the NAS and HPE server to the LAN until it the same problem occurs again.

This and the information I found online leads me to believe that the problem is cause by either or both of this two factors:

1. Cat 7 uses S/STP shielding, this shielding causes cross currents between the switch (and possibly other component is the rack) and the network cards, each coming from their own respective power circuits, because the devices I am now trying to connect are in a different room.

      2. As far as my understand goes these cross currents can either be caused naturally or by having a “leak” in the grounding due to a old practice that is called “classical grounding” or by insufficient grounding inside the server rack case.

To test point 1. I have now ordered a rJ45 modular coupling adapter that is unshielded and a rj45 Cat 6 cable that is UDP (unshielded). In this case I should be able to cut the cross current because it is not relayed over the shielding of the cable anymore. - This could solve the connection problem but the "current leaking" problem would still remain.

For nr 2. I will have to hire an electrician at some point anyway and test for possible lacks in the grounding as well as potential cross current between devices.

Will keep you updated as soon as i can test, regards
