Installing the Router
Connecting WAN, LAN, and Voice Cables
Connection Procedures and Precautions
Connect each WAN, LAN, and voice cable to the appropriate connector on the chassis or on a network
module or interface card.
•
Position the cables carefully, so that they do not put strain on the connectors.
•
Organize cables in bundles so that cables do not intertwine.
•
Inspect the cables to make sure that the routing and bend radiuses are satisfactory. Reposition cables,
if necessary.
