Figure 32 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 well 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.
If part of the AC power line is routed outdoors, use a power strip with lightning protection to connect the
AC power cord of the router to the AC power line to protect the router from being damaged by lightning
strikes.
You can attach the power strip to the rack, workbench, or wall of equipment room.
After you connect the AC power cord from the router to a socket on the power strip, verify that the green
RUN LED on the strip is on and the red LED is off.
