Acoustical noise emissions values
For open bay (no drives installed) and
maximum system configurations (14
hard disk drives installed).
v Sound power (idling):
– 5.6 bels (open bay)
– 5.7 bels (typical)
v Sound power (operating):
– 5.6 bels (open bay)
– 6.5 bels (typical)
v Sound pressure (idling):
– 44 dBA (open bay)
– 47 dBA (typical)
v Sound pressure (operating):
– 44 dBA (open bay)
– 54 dBA (typical)
These levels are measured in
controlled acoustical environments
according to ISO 7779 and are
reported in accordance with ISO
9296. The declared sound power
levels indicate an upper limit, below
which a large portion of machines
operate. Sound pressure levels in
your location might exceed the
average 1-meter values stated
because of room reflections and other
nearby noise.
