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 "Drive Module Fan Replacement" on page
254).
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.
