Why Can't I See My HIK DS-2DF843636I-AELW On My DS-7732NI-I4 NVR

I plugged the PTZ into my poe switch and can't see it on my nvr list (the poe power supply that the camera came with is plugged in nearest the camera). I have 8 other cameras already running for months on this system but there is not even any activity lights on the switch where I've plugged it in and tried other ports on the . I had it first plugged into my laptop and working fine and was able to control it with full functionality. I assigned an ip in the range of my nvr, saved it and plugged back into the switch but still no luck? Any ideas what to try next? HIK Tech Support has remoted into my setup and worked on it to resolve but are still stumped....
