Troubleshooting CSS Hardware Components

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, see the module information earlier in this chapter.

Table 2-15 provides suggestions for correcting problems that may occur with the modules.
