Hi. I have an issue with a RUT955, which is powered via 24VDC passive POE on lan 1 port. I have an external power source which is using pins  2 and 7. When going from high to low, the state switches fine. When going from low to high, the RUT955 power cycles. The input is 24VDC (pretty much exactly). I tested it originally when powering the RUT955 directly via 24V, but not when using LAN1 24v poe. Has anyone come across this?

Hello,

As I understand when you use galvanically isolated input, when powering device through PPoE going from low to high logic it reboots yours router, but if you power router directly with Power Supply Adapter, it does not reboot in same scenario? And you do not have any rules configured for router to execute on input logic change?
