Thanks for reply. The switch is out of warranty so I do no think the RMA is the right solution for me or? The mainboard itself (WS-10-250-AC) cannot be purchased as spare part...so only powersupply I could change by myself? Will you be able diagnose and repair my mainboard if there is something wrong (in different way than replace)?
Thanks for reply and assistance.
I can give you the contact info for a business up in Canada that repairs Netonix switches for $100 (average).
Just shoot me a DM if you're interested. (I have no connection to them other than as a customer)
