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.
