Configuration terminal problems

If the configuration environment setup is correct, the configuration terminal displays boot information

when the router is powered on. If the setup is incorrect, the configuration terminal displays nothing or

garbled text.

No terminal display

If the configuration terminal displays nothing when the router is powered on, check the following items:

The power supply system works properly.

The console cable is properly connected.

If no problem is found, the following reasons may apply:

The console cable is connected to an incorrect serial interface (the serial interface in use is not the

one set on the terminal).

The properties of the terminal are incorrect. You must configure the configuration terminal as follows:

set Bits per second to 9600, Data bits to 8, Parity to None, Stop bits to 1, Flow control to None, and
Terminal Emulation to VT100.

The console cable is not in good condition.

Garbled terminal display

If terminal display is garbled, check that the Data bits field is set to 8 for the configuration terminal.

No response from the serial port

If the serial port gives no response, check that the cable is in good condition and the serial port settings

are correct.

NOTE:

For more information about the serial port settings, see “

Logging in to the router and configuring basic

settings
