If a fan degrades in performance, the front panel display will show the fan’s speed. In this situation, the fan is still working, but it is not efficient. The error line displayed to the right scrolls across the bottom display row.
System Status: WARN
Errors: cage 1 fan 1 speed is below normal levels (6122.82 RPM)
If a fan completely stops working an error is reported on the front panel display. The error line displayed to the right scrolls across the bottom display row.
System Status: FAIL
Errors: cage 1 fan 1 speed is critically low (0.00 RPM)
WARNING
FIX OR REPLACE FAILED FANS AS SOON AS POSSIBLE. IF TOO MANY FANS FAIL THE
SYSTEM TEMPERATURES MAY RISE PAST AN ACCEPTABLE RANGE. IF THIS HAPPENS, THE
SYSTEM MAY TURN OFF TO PREVENT COMPONENT DAMAGE.
Figure 35 – Web Monitor Fan Failure Detection
You can use the Web monitor to detect more specific information on failing or failed fans. Once your system is displayed in the Web monitor, select “Environmental”/“Fans”. This will display a list of all fans. Please see Figure 35 for a fan failure example.
To fix a fan, determine which fan from which cage has failed – either from the front panel display or from the Web monitor. Then turn off your system and remove the lid.
