I need to disable the power over ethernet being output by a device to prevent any damage to routers and switches. After looking more into how PoE works, there appears to be two alternatives to how the power is sent over the wire.
Alternative A - Uses phantom power. This method involves sending power alongside the data signals since they are at such different frequencies.
Alternative B - Uses the unused wires of a 10/100 cable to send power.
I'm not certain as to whether the device is 10/100 or if it supports gigabit connections. If there is a way to discover the gigabit capabilities that would tell me that it cannot be alternative B. I don't have many details on the hardware, as it's part of a larger system.
