Hey all - thank you SO much in advance for your help!
I've been running two Cisco SRW208 switches to power a total of six Hik 2132s/3332s, and they've been working great for many years. I discovered the SRW208s were causing unwanted radio frequency interference and have replaced them with two used Cisco 3650CX switches, which have internal power supplies and produce zero radio interference. When I replaced the first SRW208 with a 3650, I unplugged everything from the 208 and put it all in the 3650, and all the cams came back up in a few minutes. I tried the same thing with the second switch and none of the cams that connect directly to that switch are working - all those LEDs are off on the new switch. If I plug everything back into the old switch again, they all work. Interestingly, on the troublesome switch, the cable from the OTHER switch is being recognized and is working, as is the cable to the NVR as well as the one to the internet connection; as a result, the NVR is able to see the cams from the working switch even though their signal has to run through the troublesome switch on its way to the NVR.
I was able to download the necessary USB drivers from Cisco as well as Putty and was able to do a factory reset on the troublesome switch, but it still does the same thing; changing the cables around to different ports doesn't help either. I did enable LLDP, but most of the other AI suggestions involve code that just doesn't work.
Might anybody be able to help me get this switch to recognize and power these cams? They all work fine on the old switch. Hopefully a few lines of the right code could get me up and running again! AI has plenty of theories but is almost no help with actual fixes
Thank you so very much for your help!!
