DATACOM / Accessories / PoE Injector - EPE-4818G


Discontinued, replaced by the EPA5006GP
  • 10/100/1000 Mbps Gigabit In and Out Ports
  • Supports PoE Cabling up to 300 feet
  • 48V/0.5A Power to Devices over CAT6, Cat5, and Cat5e Cabling
  • Power Output of up to 24W
  • Reliable and Sustainable Use


The EPE-4818G Power-over-Ethernet (PoE) Power Injector is designed to supply power and transmit data to PoE capable Access Points and other PoE client devices through an Ethernet cable from either a non-PoE or PoE Gigabit Ethernet Switch or port.

The EPE-4818G gives network administrators, IT managers, and installers the option to place PoE-client devices on or near ceilings or in crawl-spaces where power outlets may not be available and power Access Points or while at the same time connecting them to the company’s network. The EPE-4818G PoE injector features two Gigabit Ethernet (10/100/1000 Mbps) ports; one port for connecting to an Ethernet Switch and the other for connecting to a PoE-enabled device.

The injector uses standard IEEE pin definition to power the device and comes with a 48V/0.5A power supply. Pins 1, 2, and 3, 6 are used for data transmission while pins 4, 5, and 7, 8 are used for sending power to the device via center tap. The EPE-4818G PoE generates power over CAT6, Cat5, and Cat5e cabling of up to 300 feet. By sending out 48 V/0.5A, Ethernet terminals such as Wireless LAN Access Points can be powered remotely from an Ethernet Switch.
