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:
