power classification function.
Power Limit by Management: Tick this check box to enable/disable the port
power limit management for PoE power management.
Detect Legacy Signature: By default, the PoE switch only provides power to
the connected PD which follows the IEEE 802.3af standard. Having ticked
this check box, the legacy detection is to identify the PD (not in compliance
with the IEEE 802.3af standard) their unique electrical signatures in order for
the PoE switch can provide the power to the PD.
Priority: Set port priority for the PoE power management. 1 = C (critical), 2 =
H (High), 3 = L (Low).
Power Limit Max (mW) (<15400): Set the power limit value. The maximum
value must less 15400mW.
Fault Status: The PD error status message.
Null: It means no PD is connected or the connected PD status is normal.
Overload: It means the current is over the PD current classification
limited (475mA @ 48V DC) over 50ms.
Mode Status: The PD current operation mode status.
V sample or I sample: It means Current sample or Voltage sample.
When PD is detected and current is supplied, the PoE switch will keep
detecting and sampling some current or voltage to ensure whether the
PD is still active on the port. It is an IEEE 802.3af operating procedure.
R detect: When the port doesn’t connect with any PD, the PoE switch
will poll each port and detects the resistor.
Discovery R (ohms): Displays the resistance value.
Port Current (mA): Displays the current value.
Port Voltage (V): Displays the voltage value.
Port Power (W): Displays the watt value.
Class Current (mA): Displays current class. When the Bypass classification
is enabled, the class value will not show in here.
Determined Class: Displays power class. When the Bypass classification is
enabled, the class value will not show in here.
