Installing a lightning protector for a network port
Read the instructions for the lightning protector carefully before you install it.
The lightning protector for a network port is only applicable to a copper Ethernet port.
If part of the network cable of a copper Ethernet port must be routed outdoors, connect a lightning
protector to the cable before you plug the cable into the port.
You can install the following port lightning protectors to the router:

Installation procedure
1.
Use a double-faced adhesive tape to stick the lightning protector onto the router chassis, and
make sure it is as close to the grounding screw of the router as possible.
2.
Measure the distance between the protector and the grounding screw of the router, cut the
ground wire of the protector as appropriate, and securely tighten the ground wire to the
grounding screw of the router.
3.
Use the multimeter to measure whether the ground wire of the protector contacts well with the
grounding screw of chassis.
4.
Insert the outdoor network cable into the protector's IN end, and the cable connected to the
router into the OUT end, and examine the indicators on the lightning protector to verify that the
connection is correct.
5.
Use nylon ties to bundle the cables neatly.
