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.
