Installing A Surge Protector - HP FlexNetwork HSR6802 Installation Manual

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.

Installing a surge protector

CAUTION:
Ground the surge protector as near as possible. The grounding resistance must be less than 4
ohms. The grounding resistance must be less than 1 ohm if there are special grounding
requirements.
Read the instructions carefully before installing the surge protector.
Generally, you need to connect a surge protector before connecting a signal cable to the router. This
can protect electronic devices against surge over-voltage resulting from lightning strokes and other
interferences, and minimize impact on the router.
The surge protector is serially connected to a signal cable, so the surge protector must satisfy the
requirements of network performance indexes such as data transmission bandwidth, as well as the
lightning protection performance requirement. Before installing a surge protector, consider such
performance indexes of the surge protector as lightning protection, bandwidth, transmission loss,
and port type.

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 supply of the router.
