Figure 36 Installing a lightning protector for a network port
(1) Lightning protector
(2) Grounding cable
Installation precautions
The performance of the port lightning protector might be affected in the following cases:
•
The port lightning protector is installed in reverse direction. Connect the IN end to the outdoor
network cable and the OUT end to the network port on the router.
•
The port lightning protector is not reliably grounded. After the connection, use the multimeter to
confirm that the ground wire for the protector is as short as possible to ensure its good contact
with the grounding screw of the router.
•
The installed port lighting protectors are not sufficient. If the router has more than one network
port connected with other devices through cables outdoor, install a lightning protector for each
network port.
Connecting the AC power supply to a power strip
with lightning protection
CAUTION:
Make sure the PE terminal of the power socket has been securely grounded.
