4-Port 10/100M Passive POE power supply Advantages
► Panel 4 integrating passive POE injector suitable for powering up to eight devices.
► The RJ45 connectors on one side are connected Ethernet ports with no power (switch) on the opposite
side of the device used to connect power for Ethernet cable.
► Are used to power the two unused pairs of the Ethernet cable
► Power couples: 4.5 (positive pole) / 7.8 (negative pole)
Overview
This Power over Ethernet module allows you to power up to 4 devices remotely over ethernet wiring up
to 328 ft (100 meters) away. Add PoE ability to any Ethernet switch or router. Use this device to inject
power into the CAT-5, CAT-6 or CAT-7 cable. Standard Ethernet uses 2 of the 4 pairs, passive POE uses
unused pins 4/5 for plus power, and 7/8 for ground.Many popular devices like Cameras, IP Phones, WiFi
Access Points use this method to centralize the power source.
