The Fan Unit
The fan unit includes two redundant fans.
There are four LED indicators (
) on the front of the fan unit for fan status
monitoring.
Figure 96: The fan unit
In addition, for each fan in the unit an error LED driven by backup capacitor is
available. These two LEDs (a) are located on the top of the fan unit to indicate
the respective defective fan. The LEDs can be activated via a pushbutton (b)
after the fan unit has been removed from the chassis.
