Devices not discovered

Hi,

We have (several) OAK-D-PoE cameras with python (depthai==2.29.0.0). They're connected to a switch.

Initially we ran into several issues with the cameras not being seen, we thought it was the ethernet cables and had to redo the terminations. After this we had all cameras working for a week.

Now, as we had to restart the system, only half of them are discovered and usable from our app (python). I can still ping them all and they can be seen with arp, but dai.deviceInfo complains there's no device available

How can I tell what the problem is? Could this be a problem with the switch not being able to provide enough energy? Does that make sense?

Edit: switch is a CISCO MS250-24P-HW

we nailed it down to the cables… devices working fine with the same switch and good cables
