Connecting The Ac Power Supply To A Power Strip With Lightning Protection - H3C SR6600-X Series Manual

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.) In this case,
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 module of the router.
