Shield Ground Connections

To maintain EMC compliance, cables that are shielded and grounded at both ends must be
used with all the electrical interfaces on the router.
To meet surge protection requirements, the shield of any open-ended cable must be
grounded to a convenient chassis ground point, such as the equipment rack.

• wire stripper
• hardware for making the connection (such as a screw, star washer, and cable ties)
Locate a convenient chassis ground point, such as the equipment rack.
Carefully strip enough insulation (outer jacket) from the cable such that the exposed
grounding wire can reach the chassis ground point. Ensure that there is enough
stripped insulation to provide strain relief for the ground connection.
Caution: When stripping the cable insulation, avoid nicking the ground conductors
or the insulation on the signal conductor. Nicks can weaken or break a conductor or
expose a wire to a potential short circuit.
Separate the ground shield (braid, foil, and drain wire) from the signal conductors.
Securely attach the shield to the chassis ground point. Use a screw and star washer
large enough to make a proper ground connection. Use proper cable dressing and
strain relief techniques.
