Troubleshooting the CSS 11800 Modules
Table C-3 provides suggestions for correcting problems that may occur with the
CSS 1800 power supplies (AC or DC). The power supply status LED is on the
SCM.
Note Installing a second CSS 11800 power supply provides power load
balancing between the two power supplies. When you install a
second power supply, it powers on and begins to share the power
load automatically.
Troubleshooting the CSS 11800 Modules
Each CSS 11800 module is equipped with a temperature sensor that detects an
over- or under-temperature condition. If the module detects that its temperature is
out of range, it generates a log message.
Module status is indicated by the Status LED on the module front panel. For
information about the module LEDs, refer to Chapter 2, Cabling the CSS.
Table C-4 provides suggestions for correcting problems that may occur with the
modules.
