Claim 0:
1. A power sourcing equipment controller for providing power using power-over-Ethernet (PoE), the power sourcing equipment controller comprising:
a voltage-output logic block to output a sequence of voltage signals, wherein the voltage signals comprise at least a detection signal and a classification signal;
a current-measurement logic block to measure current provided responsive to the voltage signals;
a backoff-time-determination logic block to determine a backoff time in response to the current-measurement logic block detecting the provided current exceeding a predetermined threshold, wherein the backoff time is determined based on an amount of time needed for discharging an internal capacitor associated with the powered device; and
a timing logic block to cause the voltage-output logic block to delay the output of a next sequence of voltage signals based on the determined backoff time, thereby facilitating powering up of a device compliant with a different PoE standard.
