Appendix A - Troubleshooting 121

What to Do if the Router Does Not Work or Stops Working.

1 Check that the cables are connected correctly and firmly (see chapter 2, What is in the Box, for correct

cable connection information).

2 Confirm that the Link LED is lit, indicating proper Ethernet cable termination. If it is not lit, check both ends

of the Ethernet cable and the hub connection.

3 Confirm that the CPU LED is blinking consistently one second on, one second off. If this is not the case,

see figure A.2 for an interpretation of the blink pattern.

4 Make sure any external modem, DSU/CSU, or interface equipment is properly connected and that the

interface configuration is correct. Many cables, for example, have a DB-25 connector, but are not

interchangeable. Which cable is used for which type of modem is given in chapter 2.
