Troubleshooting CSS Hardware Components
Troubleshooting the Console Interface
Table 2-12 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
• Flow Control - none
• Parity - none
• Stop Bits -1
For information on console cable pinouts, see Appendix B, Cable Pinouts.
Table 2-12 Troubleshooting the Console Interface
Possible Problem Recommended Action
Nothing appears on the screen. Ensure 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 for 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 enough
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.
