EIPE-1 Installation Guide The EIPE PoE Power Injector in the Skorpion family offers a simple method of connecting a PoE end-device to a non-PoE 10/100 Mbps Ethernet device. The EIPE is compliant to the IEEE 802.3af standard and is considered a mid-span PSE (Power Sourcing Equipment) in that it resides between the non-PoE device and the PD (Powered Device) delivering the required 15.4 watts of power at its output connector. There are two RJ-45 connectors on the unit. The top connector, labelled Ethernet, attaches to the non-PoE device while the bottom connector, labelled Power Over Ethernet, attaches to the PD. Transmit and receive signals are freely passed between the two connectors as if the injector were not present. However, 48 VDC power is injected into the spare pins on the bottom RJ-45 connector for use by the PD. The injector does not interfere with any communication between the non-PoE device and the PD. The EIPE supports the 802.3af protocol for powering up devices. With the EIPE 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 on cable length, the PD can assume that a minimum of 12.95 watts is available at its input pins. 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.

Power Options Power Considerations Voltage in the range of 24 VAC/VDC ±10% must deliver current commensurate with 38 VA / 21 W power consumption. The recommended size for solid power conductors is 16–20 AWG; for stranded conductors, use 16–18 AWG. Zero volts (COM) is isolated from chassis (earth). Input connections are reverse-polarity protected. Network Connections Either straight-through or crossover cables can be used to connect to a non-PoE Ethernet device that supports Auto–MDI/X or to a PoE powered device. However, verify that the proper polarity of the PoE power on pins 4, 5, 7, and 8 remains intact. LED Indicators The Power LED glows solid green when the injector is properly powered. The Power Over Ethernet LED will be off if no PoE power is being applied — or solid green with PoE power being applied. This LED will flash under the following fault conditions: 1 flash — Low signature resistance received from the powered device 2 flashes — High signature resistance received from the powered device 5 flashes — Powered device drawing excessive current (overload fault) Need More Help Installing this Product?
