NOTE: Allow the enclosure to identify the PSU and determine its status. If the PSU is functioning properly, the PSU’s Power OK LED glows green and the PSU fault LED and AC fault LED are off.

Replacing fan modules

The Dell Storage MD1280 enclosure supports five fan modules. If one fan module fails, the remaining modules continue to cool the enclosure.

NOTE: When a fan module fails, the fan speed in the remaining modules increases significantly to provide adequate cooling. The fan speed decreases gradually when a new fan module is installed.

Identifying the failed fan module

To identify the failed fan module, use the secli component of the Storage Enclosure Management Software or visually verify which fan module is not functioning properly. For more information on using the secli to identify failed devices, see the Dell Storage MD1280 Administrator's Guide.
