Precautions
To ensure the performance of a port lightning arrester, follow these guidelines:
z
Correctly connect the IN and OUT ends of the port lightning arrester.
Connect the IN end to the external cable and the OUT end to the Ethernet port of the device.
z
Ensure that the port lightning arrester is well grounded.
Make sure that the grounding cable of the port lightning arrester be as short as possible and be well
connected to the grounding screw of the device. You need to check with a multimeter after
connection.
z
Install a lightning arrester for every port connected to an outdoor cable.
Installing a Power Lightning Arrester (Lightning Protection Busbar)
(Optional)
The U200 series devices are not shipped with lightning arresters for power supplies. You can purchase
one if needed.
Before connecting an outdoor AC power source directly to the device, install a lightning protection
busbar at the AC power input end and then connect the AC power cord to a lightning protection busbar
to protect the device against lightning strikes. You can use cable ties and screws to fasten the lightning
protection busbar on the rack, the workbench, or the wall in the equipment room.
