(4) IEC standard socket It is used to connect to the power supply in the equipment room through a
power cord.
(5) Overload automatic protector 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.
(6) Multifunctional socket It is used to connect the power module of the router.
Installing a lightning protector for a network port
The router does not come with any lightning protector. H3C recommends that you install lightning
protector for 10/100/1000 Mbps RJ-45 copper Ethernet ports.
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.
Required tools
• Philips or flat-blade screwdriver
• Multimeter
• Tilted wire cutter
Installation procedure
1. Use a double-faced adhesive tape to stick the lightning protector onto the router chassis, and make
sure it is as close to the grounding screw of the router as possible.
2. Measure the distance between the protector and the grounding screw of the router, cut the ground
wire of the protector as appropriate, and securely tighten the ground wire to the grounding screw
of the router.
3. Use the multimeter to measure whether the ground wire of the protector contacts well with the
grounding screw of chassis.
4. Insert the outdoor network cable into the protector's IN end, and the cable connected to the router
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 may 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 router.
• The port lightning protector is not well 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 router.
• 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.
