Connection Procedures and Precautions
After you have installed the router chassis, perform these steps to connect the WAN and LAN interfaces:
• Connect each WAN and LAN to the appropriate connector on the chassis.
• Position the cables carefully so that you do not strain 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. If necessary, reposition
the cables.
• Install cable ties in accordance with site requirements.
Configure the Router at Startup
After installing the router and connecting the cables, you can configure the router with basic configurations.
