It takes forever for the switch to establish a connection with a camera. Lights blink orange/green and go off. All those cameras worked perfectly fine on Cisco switch for years. Eventually they may or may not come up but it takes literally 1 h in some cases.
Often I had to reset the camera to factory settings to make it come up on the switch. It almost seems like establishing PoE connection is an issue. Is there anything I should be aware of? We have 120 cameras there on 5 switches. Connections seem just very unstable.
