NOTE:
• The difference between shielded twisted pair and unshielded twisted pair cables is that a
shielded twisted pair cable as a shielding layer made of aluminum foil.
• The difference between shielded RJ-45 and unshielded RJ-45 connectors is that a shielded
RJ-45 connector has a metal housing.
Procedure
The procedure is similar for shielded twisted pair and unshielded twisted pair cables. This section
uses an unshielded twisted pair cable as an example.
To attach an RJ-45 connector:
1. Use the crimping pliers to trim one end of the cable, put the cable end into the knife edge for
wire stripping, hold the wire-crimping pliers slightly and rotate slowly. Let the knife edge peel off
the insulation sleeve to expose the twisted pair.
FigureB-9 Peeling off the insulation sleeve
NOTE:
• When stripping the shield, do not scratch the insulation layer of the core wires.
• The length of the crimper stop from the stripping blade is usually exactly the length of an
RJ-45 connector, which can effectively avoid stripping the wire too long or too short.
2. Align the wires as required.

NOTE:
According to the different wiring relationship, the network cable is divided into straight-through
network cable and crossover network cable. This section uses a straight-through cable as an
example. For more information, see H3C CR16000-M Router Hardware Options.
3. Use the cutting edge of the wire-crimping pliers to trim the top of the twisted pair cable neatly.
Slowly and forcefully insert the 8 wired into the wire grooves in the RJ-45 connector at the same
time, and insert them all the way to the top of the grooves.
Make sure the wires extend to the front of the RJ-45 end and make good contact with the metal
contacts in the RJ-45 end.
