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.
Claims18
A test equipment to test power over Ethernet (PoE) function of an Ethernet device, the test equipment comprising:
- a first connector to receive data signals and power signals transmitted by the Ethernet device, the first connector comprising:
- a first group of pins to transmit the data signals and the power signals;
- a second group of pins comprising two positive power pins and two negative power pins to transmit the power signals;
- a second connector;
- a data signal transmission circuit connected between the first group of pins of the first connector and the second connector to transmit the data signals to the second connector, and to transmit the power signals;
- a first polarity determination circuit configured to receive and output the power signals when the power signals are transmitted by the data signal transmission circuit;
- a second polarity determination circuit configured to receive and output the power signals when the power signals are transmitted by the second group of pins of the first connector;
- and
- a notification circuit configured to generate a notice to indicate the PoE function of the Ethernet device is normal when receiving the power signals output by the first or second polarity determination circuit.
A test system to test the power over Ethernet function and the data signal transmission function of the Ethernet device, comprising:
- a test equipment to test power over Ethernet function of a Ethernet device, comprising:
- a first connector to receive data signals and power signals transmitted by the Ethernet devices, the first connector comprising:
- a first group of pins to transmit the data signals and the power signals;
- a second group of pins comprising two positive power pins and two negative power pins to transmit the power signals;
- a second connector;
- a data signal transmission circuit connected between the first group of pins of the first connector and the second connector, to transmit the data signals to the second connector, and to transmit the power signals;
- a first polarity determination circuit configured to receive and output the power signals when the power signals are transmitted by the data signal transmission circuit;
- a second polarity determination circuit configured to receive and output the power signals when the power signals are transmitted by the second group of pins of the first connector;
- and
- a notification circuit configured to generate a notice to indicate the PoE function of the Ethernet device is normal when receiving the power signals output by the first or second polarity determination circuit;
- and
- a data signal test module to compare the data signals received from the second connector of the test equipment with reference data signals received in a preset time to determine whether the data signal transmission function of the device is normal.
