Troubleshooting the Console Interface
Table C-2 lists common communications problems that may exist between the
CSS and a console. Ensure the console settings are configured to:
• Baud Rate - 9600
• Data Bits - 8
• Parity - none
• Stop Bits -1
• Flow Control - none
For information on console cable pinouts, refer to Appendix B, Cable Connector
Pinouts.
Table C-2 Troubleshooting the Console Interface
Possible Problem Recommended Action
Nothing appears on the screen. Ensure that the RS-232 cable is
securely connected to the console port.
Characters appear on the screen, but
are garbled.
Verify that the CSS and the console
settings match with respect to baud
rate, data bits, stop bits, and parity.
Abbreviated input is used, but pressing
the tab key does not enter the command
you want.
Ensure that you enter a sufficient
number of characters for the CSS to
distinguish between different
commands and options.
Random characters are lost. Set the flow command on the console
to XON/XOFF.
