4.16.2 Power Configuration

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.
Reserved Power determined by
There are five modes for configuring how the ports/PDs may reserve power and when to shut down ports.

Classification mode
In this mode each port automatic 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 and 30.8 Watts.

In this mode the user allocates the amount of power that each port may reserve. The allocated/reserved power for each
PoE Splitter
PoE Splitter split the PoE 48V DC over the Ethernet cable into 5/9/12V DC
power output. It frees the device deployment from restrictions due to power
outlet locations, which eliminate the costs for additional AC wiring and reduces
the installation time.
