The standard of 802.3bt introduces two innovative PD topologies - Single Signatureand Dual Signature. A “Single Signature PD” shares the same detection signature, classification signature, and maintain power signature between both pair sets, while a “Dual Signature PD” has independent signatures on each  pair set.

PD classes 5~8 are also added in 802.3bt in the range of 40W~71W, making total 9 PoE classes in total. It is also selectable for Layer 1 or Layer 2 in PSE to classify the PD which meets this feature as well (by Link Layer Discovery Protocol). In addition, under Single Signature the selection of “Autoclass” intelligently detects connected PD’s maximum power consumption and defines the class relevantly.

Sourcing from PSE, Xtramus NuPOE-4SLM provides two RJ-45 ports for each pair set to separate data and power, thus the data can be forwarded to NuStreams platform or others’ to run data test simultaneously.

Deriving from PSE, NuPOE-4SLM and its built-in cooling fans are not required to equip with external power to work, but 12V DC external power is required to drive high-speedcooling fans.

NuPOE-4SLM also supports web and telnet remote management, user can set loading for each channel through web pages or CLI, and upgrade firmware through web pages.
