No display on the configuration terminal
Symptom
After the firewall is powered on, the configuration terminal does not display anything.
Solution
To troubleshoot the configuration system failure first:
1.
Verify that the power supply system is operating correctly.
2.
Verify that the console cable is correctly 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.
If the cause cannot be located in the previous steps and the problem persists, contact your local sales
agent.
Garbled characters on the configuration terminal

field is set to 9600 bps. An incorrect setting can cause the
configuration terminal to display 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 "
