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.
