  • Power sourcing equipment chip power sourcing equipment and power over ethernet system and method using registers and slave address
    Patent number: 9223374
    Abstract: A power sourcing equipment (PSE) chip controls a powering channel of the PSE chip according to a value stored in a first register; the PSE chip changes, in response to a second instruction, the value stored in the first register into a calculated value, where the second instruction includes a second slave address and a second data byte, the second slave address is a virtual address of a virtual powering group, and the calculated value is a result obtained by calculation according to the second data byte and a channel indication value that is of the virtual powering group and stored in the PSE chip. Information indicating whether a powering channel is added to a virtual powering group is stored in a PSE chip, so that powering channels added to a virtual powering group can be controlled at a time.
