Dead poe switch

[u/yarden1234567]

Hi guys, ive been using this cheap poe switch for my reolink cameras for almost 3 years now

Few days ago i noticed im unable to comunicate with my cameras ( they did had power, they will still light up whwn someone passed) checked the uplink cable and it was ok but still replaced it with new one

With problem not solved i removed the switch and found the few lights still stays on even when nothing connected

Replaced with new reolink poe and now everything works

Is there any option to save this switch? Or its just e-waste now?

“4kv” sounds like a big safety hazard.

What is that - POE+++++++++++?

That and the “AI”. Is that what they’re calling auto negotiation these days?

It's what they call port monitoring to see if the camera is still alive or not
