24-Port (2 pair) Power Sourcing Equipment Reference Design for Multi-port
Applications
•
Power guard band: when the total allocated power < total power budget — guard band, there's no
more low priority ports to be turned on and the guard band LED will turn on.
Device configuration is mainly used to configure the mapping between the PSE device channels and the
logical RJ45 ports. When mapping a 4-pair port, only channels within the same quad (channel 1–4 or
channel 5–8) can be mapped to one 4-pair port.

The
Port Configuration
is applied to the port by port settings, such as port PoE enable and disable, port
priority, and port power limit (only in port limit mode).
