Though working with the PD emulation module, NuPOE-16EL can test the PoE performance of the DUT. In addition, it has a function of bypassing data, supporting fast Ethernet data transmission.

XL-T451 is a module specially designed for the NuPOE-M16EL chassis, acting as a PD (powered device) in the test. One NuPOE-M16EL chassis can contain 16 XL-T451 modules at most, from slot2 to slot17, which are supposed to emulate 16 PDs.
