Edit to add: the lan connections from the 4 port switches to the 16 port switch do not light up at all??
I have an 11 camera setup using Blue Iris but recently 5 of the cameras have stopped communicating over the LAN. The only thing in common is that the five cameras use TP-Link POE switches (3 cams on one switch and 2 cams on another). They did not fail at the same time. When the first one failed a few days ago, I did a lot of troubleshooting and thought the switch was failing because it was intermittent. So I replaced the switch and all was good. Today, the new switch and the other one failed at the same time. I've checked power, point to point connectivity on the cat6 cable to the switches and cameras, but the cameras do not show up on the client list and cannot be pinged. Other cameras connected to the 16 port switch are powered separately are working fine. I've attached a diagram, mainly all cams connected to the 4 port switches have failed and I don't know why? I have had this system working without issue for years.
Thanks for any help!
