Solution
To troubleshoot the configuration system failure 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.
