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. Start the Dell Storage Client and connect to the Storage Center that has an expansion enclosure with

a failed power supply.

2. Click the Hardware tab.

3. In the Hardware tab navigation pane, select and expand the Storage Center.

4. In the Hardware Alerts area, find the hardware alert that identifies the expansion enclosure with the

failed power supply.
