7.4 PoE Troubleshooting flow
If the Jack-PC device is working properly when an external power supply is connected to it,
but it is unpowered when connected to PoE capable port without the power supply, we have a
PoE problem. See the flow bellow to debug this problem.
In geneal the most important thing here is to isolate the cabling and connection components
(wiring, Flex-Jack, patch panel) and the power source (power injector or switch).
If you are unable to solve your problem, please contact Chip PC support at

Check at the far end that the port is connected to a
powered port in the switch or to a power injector
