Install the array controller so that the ventilating holes may not be
blocked. If either or both of the ventilating holes are blocked, the
internal temperature of the array controller may increase to cause a
fault to occur.
The controller is equipped with 4 fans in total. Even if a fan fails, the
air-cooling conditions for the entire array controller are satisfied.
However, to guarantee the safety operation of the disk array unit,
replace the controller cooling fan immediately if a fan failure occurs.
