Fault of Controller Cooling Fan
If a controller cooling fan is defected, the SERVICE LED on the array controller lights
orange. In addition, the FAN LED on the corresponding controller lights orange. The
defected controller cooling fan may be replaced with the power of the disk array unit
remaining ON.
<Replacement procedure>
(1) Check whether the defected controller cooling fan is FAN0 or FAN1 depending on
the FAN LED being on.
(2) Loosen the two set screws at the upper right and lower left corners of the defected
controller cooling fan to pull out it from the slot. (Note that the fan may be rotated
by inertia.)
(3) Insert the controller cooling fan for replacement into the slot.
(4) Fasten the two set screws at the upper right and lower left corners of the controller
cooling fan to fix it.
When inserting the cooling fan into the controller, push it as far as it will
go and then secure it with the screws.
Incorrect insertion may cause malfunction.
