mounting rails)
Depth: 57.9 cm (22.8 in.)
Height: 13.2 cm (5.20 in.)
Width: 48.2 cm (18.97 in.)
Weight
Typical expansion unit fully
loaded: 39 kg. (86 lbs.)
Electrical Input
Sine-wave input (50 to 60 Hz) is
required
Input Voltage:
– Low range:
- Minimum: 90 V ac
- Maximum: 127 V ac
– High range:
- Minimum: 198 V ac
- Maximum: 257 V ac
– Input kilovolt-amperes (kVA)
approximately:
- Minimum configuration:
0.06 kVA
- Maximum configuration:
0.36 kVA
Environment
Air temperature:
– expansion unit on:
10° to 35° C
(50° to 95° F)
Altitude: 0 to 914 m (3000 ft.)
– expansion unit on:
10° to 32° C
(50° to 90° F)
Altitude: 914 m (3000 ft.) to
2133 m (7000 ft.)
Humidity:
– 10% to 80%
Acoustical Noise Emissions Values
For open bay (0 drives installed) and
typical system configurations (8 hard
drives installed).
– Sound Power (idling):
- 6.2 bels (open bay)
- 6.4 bels (typical)
– Sound Power (operating):
- 6.2 bels (open bay)
- 6.5 bels (typical)
– Sound Pressure (idling):
- 47 dBA (open bay)
- 49 dBA (typical)
– Sound Pressure (operating):
- 47 dBA (open bay)
- 50 dBA (typical)
These levels are measured in
controlled acoustical environments
according 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.
