Ubiquity Access Point Experience
Have a question for the community. I have tracked down 2 signals coming from my Ubiquity UAP-AC-LR access points, one at about 3.547 and another at 3.565 on the 6600M/ V3.
They are classic SMPS signatures.... drift/ dancing etc. see pic below. I can make them come and go at will by removing their power.
I have replaced the provided Ubiquity POE SMPS with a linear power supply.
Extensively choking of the Ethernet cable on both ends (well above the threshold Z via mix 31 & 75) provided no reduction in signal amplitude. Just keeping them powered up, with Ethernet cable at switch disconnected creates these signals.
I am guessing there is another SMPS inside for 3.3 VDC for the internal circuitry that is radiating.
Before opening the case and sniffing around with the spectrum analyzer and probes, thought I would inquire to determine if anyone had this experience or point out if I have missed something.
Any input would be appreciated
