Installing a lightning protector for a network port

IMPORTANT:
Read the instructions for the lightning protector carefully before you install it.
If part of the network cable of a 10/100/1000 Mbps RJ-45 copper Ethernet port must be routed
outdoors, connect a lightning protector to the cable before you plug the cable into the port.
HP recommends that you install a lightning protector for 10/100/1000 Mbps RJ-45 copper Ethernet
ports.
The switch does not come with any lightning protector.
Required tools
Phillips or flat-blade screwdriver
Multimeter
Tilted wire cutter
Installation procedure
To install a lightning protector:
1.
Use a double-faced adhesive tape to stick the lightning protector onto the switch chassis, and make
sure it is as close to the grounding screw of the switch as possible.
2.
Measure the distance between the protector and the grounding screw of the switch, cut the ground
wire of the protector as appropriate, and securely tighten the ground wire to the grounding screw
of the switch.
3.
Use the multimeter to measure whether the ground wire of the protector contacts correctly with the
grounding screw of chassis.
4.
Insert the outdoor network cable into the protector's IN end, and the cable connected to the switch
into the OUT end, and look at the indicators on the lightning protector to verify that the connection
is correct.
5.
Use nylon ties to bundle the cables neatly.
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 switch.
The port lightning protector is not correctly 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 switch.
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 switch.
