Troubleshooting Cisco 700 Series Routers 5-5
If the router calls itself, check that the number configured with the set number command
is not the same as the number configured with the set directory number command.
Communicating with the LAN
If you have problems communicating with a 10BaseT Ethernet LAN device (such as your
PC), do the following:
•
Verify the LINK LED on the back panel of all models except Cisco 766 or Cisco 776
routers or at least one of the link (LK1, LK2, LK3, or LK4) LEDs on Cisco 766 or
Cisco 776 routers is on, indicating the router is communicating with the LAN device. If
the LED is blinking, it is attempting to establish a connection. Check the Ethernet cables
or the device attached to the other end of the cable, such as the network interface card
(NIC) in your PC.
•
Verify the LAN LED on the front panel is lit, indicating the router is communicating
with the LAN device. If the LED is blinking, it is attempting to establish a connection.
Check the Ethernet cables or the device attached to the other end of the cable, such as
the NIC in your PC.
•
Check the HUB/NODE switch located on the back panel of all models except Cisco 766
or Cisco 776 routers. This switch eliminates the need for an Ethernet crossover cable
when connecting to a hub. If it is in the wrong position, it will not cause any damage to
the equipment; however, the signals will not be sent to the correct location. If you are
connecting directly to a PC, the switch should be in the HUB position. If you are
connecting to a hub, the switch should be in the NODE position.
Note
