Modules Troubleshooting the Boot Process Log File Information Information in this appendix applies to the CSS 11050, CSS 11150, and CSS 11800 Content Services Switches except where noted. Troubleshooting the Console Interface Table C-1 lists common communications problems that may exist between the CSS and a console. For information on console cable pinouts, refer to Cable Pinouts . 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. For information on power supply LEDs, refer to Cabling the CSS .
