Power out of range? (3V)

[Dave]

hmm, the UAP-ACL uses 24 volts I think..are you setting its POE port to 24V?

[jakematic]

Yes, and yes.

[jakematic]

I thought I posted this but here it is again.

Am sure you are wondering and I was curious to make sure the cable didn't get pinched or stretched

[Dave]

I was going to suggest to change the Ethernet cable as a test...

[jakematic]

Powered off the port, changed the cable, and powered it back on.

Pre-made cable, same length.

Same results. Passes cable diagnostics, and the voltage is fluctuating again

ok, lets try below:

1) try a different port with same device
2) try a different device on same port

[jakematic]

1) Steps:
- Powered off port 1
- moved cable to port 2
- powered on port 2 24V
- wait
- same result with voltages

2) Do you want powered or non-powered in port 1, or does the above test invalidate #2 ?

[Dave]

#2), want to plug in a different POE device

[jakematic]

Plugged a UVC-G3 into port 1 while port 2 was still online.
Same fluctuations.

Powered off port 2, stabilized for a moment, then started to fluctuate again, stabilized some, and is fluctuating again just as badly.

[Dave]

how about try another set of ports, each pair of ports share an ethernet transformer on the board....try plugging into ports 3/4
