Specialty PoE Test Equipment for Electronic Equipment Manufacturers

After assembly, electronic equipment manufacturers need to test functionally of their products. They want to provide the most test coverage, in the shortest time, for the least cost. When test engineers develop product test plans, they select the most appropriate off-the-shelf general purpose test equipment available. Reach designs and manufactures custom test equipment which is a better fit than general purpose equipment. It not only reduces test time but also reduces costs.

Reach Power-over-Ethernet (PoE) Testers

Manufacturers of Ethernet Power Sourcing Equipment (PSE) such as Ethernet Switches need to test PoE power functionality during manufacturing. Once a unit is in manufacturing, companies assume it has passed tests for full compliance with the applicable standard (IEEE 802.3, proprietary, or a mix of both). It is neither cost-effective nor necessary to perform full compliance testing at the manufacturing stage. Rather, what is needed is a functional test that verifies the software’s ability to detect and control power, and the connectors’ and magnetics’ ability to provide power and pass data.

The Reach RT-PoE tester family is designed to do a cost-effective, functional production test. It assumes the PSE can operate in a “diagnostic” mode to check the power control and detection functions of the PSE individually. To keep the cost of the tester low, the LLDP protocol specified by the 802.3at standard is not supported. This protocol covers allocation of power and is mainly a software function which tested at the Design Verification step.

RT-PoE3N Power-over-Ethernet (IEEE 802.3af/at) Tester

The Reach Model RT-PoE3N provides diagnostic functional testing of 24 PSE ports compatible with IEEE Standards 802.3af and 802.3at. It can draw up to 720mA per port while passing gigabit traffic. It provides high density with 24 Powered Device (PD) loads in a 1U high chassis.The Reach Power-over-Ethernet Tester Model RT-PoE3NL/8 has 8 ports instead of 24 ports, but is otherwise the same as the RT-PoE3N.

Each PoE section has a “UUT” and a “REF” port. The UUT port is connected to the PSE and acts as a PD load to that port. The UUT datapath is connected via power-isolating magnetics to the REF port. In this way, an external data bit error tester or PSE test functionality can be used to test data integrity while power load is enabled.

RT-PoE4N Power-over-Ethernet (IEEE 802.3af/at/UPoE/PoE++) Tester

The Reach Model RT-PoE4N provides production testing of 24 PSE ports compatible with IEEE Standards 802.3af and 802.3at as well as proprietary UPoE and PoE++ implementations. It can draw over 600mA on up to two power pairs per port (over 60W per port) while passing gigabit traffic. It provides high density with 24 Powered Device (PD) loads in a 1U high chassis.The Reach Power-over-Ethernet Tester Model RT-PoE4N/8 has 8 ports instead of 24 ports, but is otherwise the same as the RT-PoE4N.To reduce cost, the datapath of each UUT port is connected to its neighbor for loopback testing (port 1 – 2, 3 – 4, etc). Data traffic is either generated by the switch if it has diagnostic ability, or externally and routed through each port by using the appropriate VLAN configuration.
