Environment
v Air temperature:
– Storage server on:
10° to 35°C
(50° to 95°F)
Altitude: 0 to 914 m (3000 ft)
– Storage server on:
10° to 32°C
(50° to 90°F)
Altitude: 914 m (3000 ft) to 2133 m
(7000 ft)
v Humidity:
– 8% to 80%
Acoustical noise emissions:
For maximum system configurations (14
hard disk drives installed).
v Sound power (operating): 5.7 bels
(typical)
v Sound pressure (operating): 42 dBA
(typical)
Note: These levels were measured in
controlled acoustical environments
according to the procedures specified by
the American National Standards Institute
(ANSI) S12.10 and ISO 7779 and are
reported in accordance with ISO 9296.
Actual sound-pressure levels in a given
location might exceed the average values
stated because of room reflections and
other nearby noise sources. The declared
sound-power levels indicate an upper limit,
below which a large number of computers
will operate
