Garbled terminal display

Symptom
The configuration terminal displays garbled characters when the router is powered on.
Solution
Verify that the Data bits field is set to 8 for the configuration terminal. If the Data bits field is set to 5
or 6, the configuration terminal displays garbled characters.

No response from the serial port

Symptom
No boot information is displayed on the configuration terminal when the router starts up or restarts
up.
Solution
Verify that the serial cable is in good condition and the serial port settings are correct.

Restoring the factory settings

Scenario 1

Symptom
When you replace the router, the router password is lost. As a result, you cannot log in to the router
and do not know the router configuration.
Solution
Because the router is replaced, you do not need to save the configuration of the router. In this case,
you can press the RESET button for more than 4 seconds to reboot the router and restore the factory
settings. Then, you can use the username and password shipped with the router to log in to the
router.
When the router configuration must be saved and you have a console cable, you can log in to the
router through the BootWare menu.

Scenario 2

Symptom
After the configuration is modified, the network connectivity is lost. When you check the configuration,
the configuration is very complicated and it is hard to locate the errors. In this case, you must
configure the router again.
Solution
If you have not saved any configuration, you can reboot the router by pressing the RESET button for
a short time or power off the router.
