User’s Manual of ISW-1022M Series and ISW-1033MT
AC Disconnect
Tick this checkbox to monitor the AC impedance on the port terminals and
removes power when the impedance rises above a certain value, for a certain
period (for details, see the IEEE 802.3af specification).
Capacitive Detection
If the port and capacitive detection are enabled, the capacitances state reads
in the voltage result from the constant current. This is then subtracted from the
pre-capacitance voltage to get a charge rate. If this charge rate is within the
window of the PD signatures, the device is considered to be discovered.
Start
Showing with a tick symbol, the system initializes and resets successfully.
Port
The index of PoE ports.
Enable State
Check it to enable the PoE function to the port.
Power Limit From
Classification
Check it to decide the power limit method.
When this check box is ticked, the system will limit the power supply to the
powered device in accordance with the related class.
Legacy
Check it to support the legacy power devices.
Priority
Pull down the selection menu item to choose the priority of power supplying.
„ Critical
„ High
„ Low
High priority is “Critical”.
Port Limit (<15400) mW
User can key in the power limit value which is under 15.4 Watts.
Mode
Displays the operating mode of the port.
Current (mA)
Displays the operating current of the port.
Voltage (V)
Displays the operating voltage of the port.
Power (mW)
Displays the power consumption of the port.
Determined Class Displays the PD’s class.
Class 0 is the default for PDs. However, to improve power management at the
PSE, the PD may opt to provide a signature for Class 1 to 3.
The PD is classified based on power. The classification of the PD is the
maximum power that the PD will draw across all input voltages and
operational modes. A PD shall return Class 0 to 3 in accordance with the
maximum power draw as specified by Table 5-9-1.
And then, click Apply to carry into effect.
