Heatsink

The heatsink fins accumulate dust from the cooling air. Since a dusty heatsink is less
efficient at cooling the drive, overtemperature faults become more likely. In a
"normal" environment (not dusty, not clean) check the heatsink annually, in a dusty
environment check more often.
Clean the heatsink as follows (when necessary):
1. Remove power from drive.
2. Remove the cooling fan (see section "Main Fan Replacement" on page 212).
3. Blow clean compressed air (not humid) from bottom to top and simultaneously use a
vacuum cleaner at the air outlet to trap the dust.
Note: If there is a risk of the dust entering adjoining equipment, perform the cleaning
in another room.
4. Replace the cooling fan.
5. Restore power.
