Connection Procedures and Precautions
To properly connect cables follow these steps:
Connect each WAN and LAN cable to the appropriate connector on the chassis or on an interface card.
Step 1
Position the cables carefully, so that they do not put strain on the connectors.
Step 2
Organize cables in bundles so that cables do not intertwine.
Step 3
Inspect the cables to make sure that the routing and bend radius is satisfactory. Reposition cables, if
