ABSTRACT:
A test equipment to test power over Ethernet (PoE) function of an Ethernet device comprises a first connector, a second connector, a data signal transmission circuit, a first polarity determination circuit, a second polarity determination circuit and a notification circuit. The first connector receives and transmits data signals and power signals transmitted by the Ethernet device. The data signal transmission circuit transmits the data signals to the second connector and outputs the power signals. The first and second polarity determination circuits receive and output the power signals to the notification circuit. The notification circuit receives the power signals and consequently generates a notice to indicate the PoE function of the Ethernet device is normal.
