Chapter 3 Installing and Connecting the Router
Connecting WAN and LAN Interfaces
Ports and Cabling
summarizes typical WAN and LAN connections for Cisco 2010 CGR routers. The connections
summarized here are also described in detail in
Modular Access Router Cable Specifications
.
Connection Procedures and Precautions
To properly connect cables follow these steps:
Step 1
Connect each WAN and LAN cable to the appropriate connector on the chassis or on an interface card.
Step 2
Position the cables carefully, so that they do not put strain on the connectors.
Step 3
Organize cables in bundles so that cables do not intertwine.
Step 4
Inspect the cables to make sure that the routing and bend radius is satisfactory. Reposition cables, if
necessary.
Note
Install cable ties in accordance with site requirements.
