Chapter 3      Connecting the Router
  Verifying Connections
Step 2 Plug the adapter cord into the router.
Note The power adapters have 18 AWG wires for the input connection. Tinned bare wires are used for 
the input connection as there is no standard established for connector type. Screw terminal 
blocks are most often used.
Verifying Connections
To verify that all devices are properly connected to the router, first turn on all the connected devices, 
then check the LEDs. To verify router operation, refer to 
Table 3-1.
For full LED description, see Table 1-5.
