The Ventilation Concept
The system is kept cool by three fans in each power supply unit, two fans in the
rear fan module, and five fans in the front panel.
When a fan fails, the amber front identify LED (see figure 15 on page 42) on the
front panel blinks. You can find out which fan module is defective by checking
the fan status via the server management software
ServerView

Even though the system can continue operating with a defective fan, the
defective fan module or power supply unit must be replaced within a
reasonable amount of time.
For how to replace a power supply unit see section “Replacing a Power
Supply Unit” on page 119.
Due to the hot-swap architecture, replacement is also possible during operation.
