LAN, WAN, and Voice Connection Procedures

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 such that cables do not intertwine.

•Inspect the cables to make sure that the routing and bend radiuses are satisfactory. Reposition cables, if necessary.

•Install cable ties in accordance with site requirements.

For cable pinouts, refer to the online document Cisco Modular Access Router Cable Specifications.
