No display on the configuration terminal
Symptom
After the firewall is powered on, the configuration terminal does not display anything.
Solution
Follow these steps to troubleshoot the configuration system failures first:
1. Verify that the power supply system is operating properly.
2. Verify that the console cable is properly connected.
If the cause cannot be located in the steps above, the possible reasons are as follows:
• The console cable is connected to an incorrect serial port (the serial port in use is not the one set
on the configuration terminal).
• The properties of the configuration 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 broken.
Garbled characters on the configuration terminal
Symptom
After the firewall is powered on, the configuration terminal displays garbled characters.
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.
• Verify that he AUX port is operating in flow mode when the AUX port is used as a backup for the
console port. For more information about the AUX port, see "
Logging in to the CLI through the AUX
port ."
For how to set the properties of the serial port, see " Configuring communication parameters on the
terminal ."
