Troubleshooting the CSS 11501 Chassis Fans
The CSS 11501 has six fans. When the CSS starts up and the fans are operational,
the following message appears:
CHMGR: All fans are present (6).
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 11501 starts up, or fails during its normal operation,
the following message appears:
CHMGR: Missing fans. Expected 6. Found number.
The number variable indicates the total number of functioning fans. If the
CSS 11501 starts to overheat, the following message appears:
Temperature has reached x celsius for slot number
The x variable indicates the temperature of the CSS 11501.
When a fan failure occurs, obtain technical assistance.
