Chapter 5. PoE Management (ES0152P
2. Class mode: In this mode each port automatically determines how much
power to reserve according to the class the connected PD belongs to, and
reserves the power accordingly. Four different port classes exist and one for 4,
7, 15.4 or 30 Watts.
In this mode the Maximum Power fields have no effect.
3. LLDP-MED mode: This mode is similar to the Class mode expect that each
port determine the amount power it reserves by exchanging PoE information
using the LLDP protocol and reserves power accordingly. If
no LLDP information is available for a port, the port will reserve power using
the class mode
In this mode the Maximum Power fields have no effect
For all modes: If a port uses more power than the reserved power for the port,
the port is shut down.
Power Management Mode:
There are 2 modes for configuring when to shut down the ports:
1. Actual Consumption: In this mode the ports are shut down when the actual
power consumption for all ports exceeds the amount of power that the power
supply can deliver or if the actual power consumption for a given port exceeds
the reserved power for that port. The ports are shut down according to the ports
priority. If two ports have the same priority the port with the highest port
number is shut down.
2. Reserved Power: In this mode the ports are shut down when total reserved
powered exceeds the amount of power that the power supply can deliver. In this
mode the port power is not turned on if the PD requests more power than
available from the power supply.
