WS-12-250-DC won't power up

[kennaster]

See description below. Is there a internal circuit reset on the WS-12-250-DC or is this switch fried?


"Friday morning I tested out the new ethernet cable + splitter + voltage converter + stardot camera. Something went wrong.
1) I pulled a 48 VDC -> 12 VDC converter from an unused set up. I confirmed at this point that the converter was receiving 48VDC from the power supply and putting out 12VDC.
2) I put the converter in line with the power jack on a static POE splitter. I plugged the jack on the splitter into the 48V side of the converter, and plugged the 12V end of the converter into the camera. I also plugged the ethernet part of the splitter into the camera.
3) I signed onto the netonix switch with my laptop and turned port 3 on, to 48V (.75A).
4) I plugged the 70ft ethernet cable I made into the POE splitter, then into the switch. At this point all the power on the switch went out."

Thanks again,
AK

Edit: Performed cold reset. no response after 5min.

You should NEVER plug a cable into a port with POE turned on.

If something is wrong it will damage the switch, the switch has the ability to detect a cross short and refuse to turn POE on.

My guess is the switch board is toast but can not tell until you RMA it.

RMA the unit.

Okay, this was my guess. Good help is hard to find these days. I'll set up an RMA now.
Thanks
