Step 9: Ground the Device
To ensure proper grounding, use the grounding point situated at the bottom corner of the device and the grounding screw
provided to attach a ground wire of atleast 12 AWG stranded to the device. It is important that the following grounding
guidelines are followed to protect the device against lightning or ESD events:
1. Connect one end of the grounding cable to the device and the other end to the closest earthing system point at the
installation.
2. Cut any extra ground wire length when finished connecting it to the single point earth ground.
3. Avoid sharp bends and never loop or coil up the ground wire, always connect it straight to ground.
4. A good earth ground impedance is less than 1.0 ohm.
5. Make sure all connections are fastened securely and are tight.
6. Never install during a storm and always follow your local safety codes.
Connect the grounding wire, which is supplied with the product package, to the grounding lug as shown below:
Step 10: Power ON the Device
Plug in the power cord into a power outlet after having connected the PoE Injector and the device using Cat5/5e or better
cable. There is no ON/OFF switch on the device. To disconnect power, unplug the RJ45 connector from the LAN+DC port on
the PoE injector.
: When you power ON the device, LEDs on the scaling mask glow. The more LEDs on the scaling mask glow, better is
the signal. For better signal strength, try adjusting the position of the device.
The number of LEDs glowing and their corresponding SNR ranges are as follows:
