We've got 2 PTZ1 cameras and they aren't properly working with Cisco POE+ switches. I've tried both a Catalyst 2960X and 3850 and they'll provide 15watts but won't negotiate any more power. We'll get video signal like this but don't get PTZ function. Having read documentation on POE+ implementation there's 2 ways to negotiate more power, one through signature resistors, and another through lldp. I've monitored traffic from the camera and there's no lldp packets at all. Does anyone know how the PTZ1 camera implement POE+? Has anyone got this working on a Cisco switch? I did another test on a Juniper EX4200 switch and everything works, but I'd rather use the Cisco.
