Acoustical noise emissions
values
For open bay (no drives installed)
and maximum system
configurations (14 hard disk
drives installed).
• Sound power (idling):
— 5.6 bels (open bay)
— 5.7 bels (typical)
• Sound power (operating):
— 5.6 bels (open bay)
— 6.5 bels (typical)
• Sound pressure (idling):
— 44 dBA (open bay)
— 47 dBA (typical)
• 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.
