POWERED DEVICE CLASSIFICATION IN A WIRED DATA TELECOMMUNICATIONS NETWORK

摘要

In a wired data telecommunication network power sourcing equipment (PSE) coupled to a powered device (PD) carries out an inline power discovery process to verify that the PD is adapted to receive inline power, then a plurality of classification cycles are carried out to convey a series of inline power classes back to the PSE. The series of inline power classes may all be the same, in which case the PD is legacy equipment and is adapted to receive the power level corresponding to that class. If they are not all the same, information is thus conveyed to the PSE which may, for example, correspond to a specific power level to be applied or to other information.

1. A method comprising:
identifying a powered device (PD) receiving inline power from and coupled to power sourcing equipment (PSE) in a wired data telecommunications network; sending a request for priority from the PD to the PSE by interrupting, at the PD, a flow of inline power between the PSE and the PD in response to a security alert input; initiating an inline power discovery cycle in response to the interrupting; and presenting at the PD, in response to the security alert input, an identification network corresponding to the request for priority.
