Replacing Power Supply/Cooling Fan Modules

The SC100/SC120 expansion enclosures support two 700 W AC hot-swappable power supply/cooling
fan modules. The fans that cool the expansion enclosure and the power supplies are integrated into a
module and cannot be replaced separately. If one module fails, the second module continues to provide
power to the expansion enclosure.
NOTE: When a power supply/cooling fan module fails, the fan speed in the remaining module
increases significantly to provide adequate cooling. The fan speed decreases gradually when a new
power supply/cooling fan module is installed.

Identifying the Failed Power Supply

To determine which power supply failed, use the Dell Storage Client.
1. Click the Hardware tab.
2. In the Hardware tab navigation pane, select the Storage Center.
3. Expand the failed expansion enclosure entry.
4. In the Hardware Alerts area, find the hardware alert that identifies the enclosure with the failed
power supply.
