Lightning protection
Connecting the AC power supply to a power strip
with lightning protection
If part of the AC power line is routed outdoors, use a power strip with lightning protection to connect
the AC power cable 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 cable 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.
If the red LED is on, use a multimeter to check the polarity of the wires in the power socket for wrong
connections. If the zero wire (left) and the live wire (right) are correctly connected, check for missing
grounding connection.
CAUTION:
Make sure the PE terminal of the power socket has been securely grounded.
