Replacing a ZS4-4 Fan Module
Fan modules cool the motherboard and its components. The fan modules are arranged in
stacked pairs (a front row and a back row) to provide redundancy. If you remove a failed fan
module, replace it immediately. Fan modules are hot-swappable and can be removed and
installed while the storage controller is running without affecting other hardware capabilities.

Hardware in the BUI and click the associated locator icon , or go to the
