Ports and Cabling
summarizes typical WAN, LAN, and voice connections for routers. The connections
summarized here are also described in detail in the document on Cisco.com:
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 radius is satisfactory. Reposition cables, if
necessary.
•
Install cable ties in accordance with site requirements.
