5.1.5. Port Boxes
The port boxes display port status and have controls for configuring and controlling the ports.
Figure 13. Port Box
5.1.5.1. Port Status
A port box displays the results of the last detection and last classification in the middle of the right pane. The
PwrEnable LED (bottom left) is bright red if the port is turned on. The PwrGood LED is bright red if the measured
port voltage is good.
The amount of current drawn from the port is displayed at the bottom right corner of the port box. The user may
manually update the port current reading by clicking on the “R” (read) button.
5.1.5.2. Port Configuration
A port box contains four radio buttons to configure the mode of the port. The port mode may be Shutdown, Manual,
Semi-auto, or Auto.
The port features can be configured with the four checkboxes on the right pane. If “Disconnect enable” is checked,
the port removes power if the powered device is unplugged. If “PoE+” is checked, then the port supplies high
power to a powered device that follows to the PoE+ protocol. If “Low priority” is checked, the port immediately
removes power if the “Shutdown low priority ports” button is clicked. If “Legacy enable” is checked, then the port
supplies power to a legacy powered device even though the powered device does not provide a valid detection
resistance. The “Legacy enable” check box is disabled if the Si3452 controller does not support this feature.
The user may configure a port's Icut level with the “Icut (mA)” drop-down box. The port automatically removes
power if the port current is greater than the Icut level for more than 60 milliseconds.
5.1.5.3. Port Control
A port box contains three buttons for controlling a port. The “On” button forces a port to supply power; the “Off”
button forces a port to remove power, and the “Reset” button resets a port.
