POE_ERROR_PORT_NCSI	Communication problem with Ethernet controller (not PoE related)
POE_ERROR_POE_CLASS	Invalid PoE Class.
POE_ERROR_POE_VOLTAGE_FAULT	PoE voltage fault.
POE_ERROR_POE_CURRENT_FAULT	PoE over-current condition.
POE_ERROR_POE_THERMAL_FAULT	PoE over-temperature condition.

State of the PoE port, used by GetPortState()

Enumerator
POE_STATE_OFF	The PoE port is not powered.
POE_STATE_SEARCHING	Waiting for connected PoE device.
POE_STATE_POWERED	The connected PoE device is powered.
POE_STATE_OFF_MAXPWR	The total maximum power budget has been exceeded.

VIB::PowerOverEthernet::PowerOverEthernet ( )

Default constructor for the device object

The device must be opened with Open() before it can be used.

bool VIB::PowerOverEthernet::GetNumberOfPorts ( unsigned int & NumberOfPorts )

Return the number of ports

Parameters

NumberOfPorts contains the number of PoE ports

Returns: true for success, use VIBSystem::GetLastErrorString() for an error description

bool VIB::PowerOverEthernet::GetPortState	(	const unsigned int	PortIndex,
		VIB::PowerOverEthernet::POE_STATE &	State,
		unsigned int &	Error,
		unsigned int &	PoEClass
	)

Returns the current state of the given port

Parameters

PortIndex	Port index 0 ... (GetNumberOfPorts() - 1)
State	Current PoE state
Error	Pending error flags, multiple bits can be active, see POE_ERROR
PoEClass	PoE power class used by the device, valid if State is POE_STATE_POWERED

Returns: true for success, use VIBSystem::GetLastErrorString() for an error description
