Figure2-15 Grounding the device by burying the grounding conductor into the earth
(Optional) Installing network port lightning
protectors
CAUTION:
If part of the network cable for a network port is routed outdoors, install a network port lightning
protector for the port to protect against damages caused by lightning strikes.
IMPORTANT:
•
Before installing a network port lightning protector, read the instructions in the document that
comes with the protector.
•
Network port lightning protectors are available only for 10/100M/1000M RJ-45 Ethernet copper
ports.
•
If multiple network ports have network cables routed outdoors, install a network port lightning
protector for each network port.
No network port lightning protectors are provided with the device. Purchase them yourself as
required.
To install a network port lightning protector for a network port:
1.
Use a double-faced adhesive tape to stick the network port lightning protector onto the device
chassis, and make sure it is as close to the grounding screw of the device as possible.
2.
Cut the ground wire of the protector to a length (as short as possible) as required by the
distance between the protector and the grounding screw of the device. Attach the ground wire
securely to the grounding screw of the device.
Make sure the grounding screw of the device is grounded reliably.
3.
Use a multimeter to verify that the ground wire of the protector makes good contact with the
grounding screw of the chassis.
4.
Insert the outdoor network cable into the protector's Surge end marked
IN
, and insert the cable
from the network port into the Protect end marked
OUT
.
5.
Examine the port LED to verify that the port is operating correctly.
