Port Specific Control

Port Enable: enabling the port. This function is co-responding with “Master

Enable” function.

Bypass Detection: bypass the detection function. Normally the system will try to detect the 25kresistor in an 802.3af compliant PD device. If the PD doesn’t follow by IEEE 802.3af standard, you can enable this option to skip the detection on PD. When you enable this function, the system will not perform the 25resistor detection for PD and directly transmit the power to PD. This function can be cooperating with “PD discover R (ohms)” function in System setup & Control section for non-standard compliant PD device.

[Note] after setting the Bypass Detection function, please unplug and then plug in the PD device.

Bypass Classification: the system will skip the power classification and directly transmit the power to PD when this function is enabling. Normally the system will try to classify the 802.3af compliant PD device by checking the current class level. The following table is a standard current classification level table.

[Note] after setting the Bypass Classification function, please unplug and then plug in the PD device.
