The alarm is sounding and the fan indicator is red

If a fan either stops working or is slowing below optimal speed theActiveRAID will sound an alarm indicating the failure. On the rear of the unit you should see the fan that has failed, indicated by its Active logo turned red. If you have a spare parts kit you can hot swap the fan. If you don't have a parts kit, call 1-877-MAC-DISK and one of our support associates will work with you on a replacement.
