The Ernitec Electra-PoE Injector is designed to provide power and data over Ethernet (PoE) to compatible devices such as AP routers, IP cameras, and IP phones. Ensure your network cable length does not exceed 100 meters. If you encounter issues, verify the power supply, cable connections, and that the connected device (PD) power requirements do not exceed the injector's output capacity.
Product Description
This industrial PoE injector complies with IEEE 802.3af/at/bt standards. It supports automatic detection of PoE-compliant devices and matches power output accordingly. It is suitable for network environments lacking nearby power outlets.
Specifications
- Models: Electra-PoE-1GB-60W (60W output), Electra-PoE-10GB-90W (90W output).
- Network Protocols: IEEE 802.3, 802.3u, 802.3ab, 802.3x, 802.3ae.
- Network Media: Cat5 UTP (<=100m) or Cat6e (10000BASE-TX).
- PoE Standards: IEEE 802.3af, 802.3at, 802.3bt.
- Working Environment: Temperature -20 to 50°C; Storage -40 to 85°C; Humidity 5-95% (non-condensing).
- Protection: 6kV surge protection, IP20 protection grade.
Product Application
The injector connects between a network switch and the powered device (PD). Connect the switch to the 'Data in' port and the PD (e.g., PTZ camera, mini PC) to the 'PoE out' port. Ensure the device is properly grounded using the shell grounding screw on the rear panel.
Troubleshooting
- Power indicator light off: Check if the switch is connected to the power supply and that the input voltage meets requirements.
- Access port light off: Ensure the switch is connected to the access device and the network cable length is 100 meters or less.
- PoE port not powering PD: Verify the device is PoE-compatible. Ensure the power required by the PD does not exceed the maximum output of the PoE port.
