  • 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.
