Power over Ethernet (PoE) is a technology that enables the transmission of both data and power to network devices over a standard Ethernet cable, eliminating the need for additional power supplies. PoE+ is the new IEEE 802.3at PoE standard. It allows switch manufacturers to increase port power output to 30W and will replace the current IEEE 802.3af standard of 15W. The new 802.3at standard is backward compatible and supports legacy devices that comply with the 802.3af standard.

Based on the RJ45 connector, the design incorporates a PoE+ controller chip to manage and deliver 30W of power over Ethernet. It also includes magnetic media for Gigabit PoE+ to enable 10/100/1000 Ethernet speeds, thermal management, and a high level of protection against electrical stress (ESD), electrical fast transients (EFT), and electromagnetic interference (EMI). The ICMs are available with two bi-color LEDs per port, capable of indicating up to eight different operating states. The HyperJack PoE+ PSE module design also complies with PoETec V2.0 specifications with a standardized form factor and register set, enabling easy upgrades and product expansion.

The integrated PSE connector modules offer engineers flexible port configurations and a rapid migration path from non-PoE to fully integrated PoE+ designs. They simply provide a 51–56 V and 3.3 V power supply to automatically manage and control the power to connected Ethernet devices, such as VoIP phones, wireless access points, and security cameras. Additional management functionality is available via the I²C interface .
