While I wait for my installer to get back to me I thought I'd try to educate myself as to why my Rack2 "could" be overloading its 24vdc channel of my C2N-SPWS300?
It's been working in its spot for about 6 years.
I had a UPS go boom a week ago and just replaced it. Everything was working fine until I noticed my iPad wasn't able to connect to the Rack2.
I pulled it out and saw "overload" lit. I reset it... the Rack2 blinked a couple times and then the overload came back on. When I unplug the Rack2 and reset the SPWS300's channel resets fine. When I plug the Rack2 back in it overloads again.
