The Power Injector supports the 802.3af protocol for powering up devices. With the Power Injector powered up, an Ethernet cable is attached to the PD. No power is applied to the PD until a valid 25 kΩ resistance, called the signature, is sensed by the Power Injector. Once this value is sensed, the Power Injector applies power to the unused pairs thereby powering the PD. Depending upon cable length, the PD can assume that a minimum of 12.95 watts is available at its input pins.

Like all other Skorpion products, the Power Injector is powered from a 24 VAC/VDC source using a 4-pin removable connector. Provisions exist for redundant power sources. The internal isolated power supply develops the required 48 VDC PoE power eliminating any concerns regarding grounded primary power.

The EIPE utilizes a rugged metal enclosure and metal DIN-rail clip for control panel mounting
