4.5 Power over Ethernet

Power Management:
In a power over Ethernet system, operating power is applied from a power source (PSU-power supply unit) over the LAN
infrastructure to powered devices (PDs), which are connected to ports. Under some conditions, the total output power
required by PDs can exceed the maximum available power provided by the PSU. The system may a prior be planed with a
PSU capable of supplying less power than the total potential power consumption of all the PoE ports in the system. In order
to maintain the majority of ports active, power management is implemented.
The PSU input power consumption is monitored by measuring voltage and current .The input power consumption is equal
to the system's aggregated power consumption .The power management concept allows all ports to be active and activates
additional ports, as long as the aggregated power of the system is lower than the power level at which additional PDs
cannot be connected .When this value is exceeded, ports will be deactivated, according to user-defined priorities. The
power budget is managed according to the following user-definable parameters: maximum available power, ports priority,
maximum allowable power per port.
