Troubleshooting the CSS Power Supply

• Power LED on the CSS 11050 and CSS 11150
• PS1 and PS2 LEDs on the SCM in the CSS 11800
For information on power supply LEDs, refer to Chapter 2, Cabling the CSS.
Table C-2 provides suggestions for correcting problems that may occur with the
CSS 11050 or CSS 11150 power supply.
Table C-1 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.
