Troubleshooting the CSS 11506 Fan Module
The CSS 11506 has three fans in a single fan module. When the CSS starts up and
fans are operational, the following message appears:
CHMGR: All fans are present (3).
Note
This message is displayed only if the logging level is set to the Info-6 or Debug-7
level.
If a fan fails when the CSS starts up, or fails during its normal operation, the
following message appears:
CHMGR: Missing fans. Expected 3. Found number.
The number variable indicates the total number of functioning fans.
If the modules start to overheat in the chassis, the following message appears:
Temperature has reached x celsius for slot number
The x variable indicates the temperature of the module. The module in the
designated slot number is running a temperature that is too high.
When a fan failure occurs, you must replace the fan module to prevent the CSS
modules from overheating.
