The Digitus 15-W-PoE-Injektor is designed to extend your network to areas without power outlets by providing power and data over a single Ethernet cable. It is fully compliant with the IEEE 802.3af standard. Ensure your powered device (PD) is also IEEE 802.3af compatible before installation.
Product Overview
The device features three main connection points:
- 1. LAN Port: Connects to your network switch or router.
- 2. PoE Port: Connects to the powered device (e.g., IP camera, wireless access point).
- 3. AC Input: Connects to the power supply.
The device includes a PoE LED indicator. If the LED is green and lit, the device is receiving power.
Installation
Follow these precautions to ensure safe operation:
- Do not install the device near water or in damp areas.
- Ensure the device is placed on a stable surface or securely mounted.
- Maintain adequate ventilation around the device; do not block air vents.
- Verify that the power supply voltage matches the device requirements (100-240V AC).
- Do not open the device housing while it is in operation.
Mounting Options
- Desktop: Place the device upright on a stable workbench.
- Wall Mounting: Use the mounting holes on the device to hang it securely on two screws fixed to the wall.
Operation
To set up the injector:
- Connect the power cable to the AC input.
- Connect your network source (switch/router) to the LAN port using an Ethernet cable.
- Connect your powered device (e.g., IP camera) to the PoE port using an Ethernet cable.
- The device will initialize automatically upon receiving power.
