Replacing Power Supply/Cooling Fan Modules

The SCv2000/SCv2020 storage system supports two hot-swappable power supply/cooling fan modules.

The cooling fans that cool the storage system and the power supplies are integrated into the power

supply/cooling fan module and cannot be replaced separately. If one power supply/cooling fan module

fails, the second module continues to provide power to the

storage system.

NOTE: When a power supply/cooling fan module fails, the cooling fan speed in the remaining

module increases significantly to provide adequate cooling. The cooling 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 and expand the failed storage system.

3. In the Hardware Alerts area, find the hardware alert that identifies the enclosure with the failed

power supply.
