Classification: CPC H | IPC H

Claim 10:
11. A method for providing power from a power sourcing equipment controller using power-over-Ethernet (PoE), the method comprising:
outputting, by the power sourcing equipment controller, a sequence of voltage signals, wherein the voltage signals comprise at least a detection signal and a classification signal;
measuring current provided responsive to the voltage signals;
determining a backoff time in response to detecting the provided current exceeding a predetermined threshold, wherein determining the backoff time comprises computing an amount of time needed for discharging an internal capacitor associated with the powered device; and
delaying a next sequence of voltage signals based on the determined backoff time, thereby facilitating powering up a device compliant with a different PoE standard.
