Foam Fillers

If you ordered a array with fewer than three disk drives, foam fillers occupy the
empty disk drive slots. The foam fillers are air baffles that enable the to maintain
maximum cooling. If any slot does not contain a disk drive, you must fill the slot
with a foam filler to ensure proper cooling.
Caution – If the array is running and a drive slot does not contain a disk drive or
foam filler, the array cannot cool properly and might overheat.
