2.1.1 Front Vents
The enclosure that houses the xStack Storage Array contains a set of three hot-swappable
fans located in the mid-section of the chassis drawing air into vents in the front of the unit,
cooling the hard drive array and other components. This air exits the chassis through a grill
located at the rear of the chassis. It is advised that the unit only be operated with the top
cover in place. When installing the xStack Storage Array, please be sure these vents are not
blocked.
A fully loaded array with all drive bays filled can generate a significant
amount of heat. Please be sure the cover is in place to provide the forced
air flow required for proper cooling.
