Connecting The Ac Power Supply To A Power Strip With Lightning Protection - H3C SR6604 Installation Manual

•
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.
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.

On means the circuit is operating correctly; off means the circuit is damaged.
On indicates a wrong wire connection (the wire is not grounded or the live
line and null line are reversely connected), and you need to check the power
supply line.
It is used to connect to the power supply in the equipment room through a
power cord.
The protector automatically opens the electric circuit when the current
exceeds the threshold and closes the electric circuit when the current drops
below the threshold.
It is used to connect the power supply of the router.
