68 Environmental requirements and specifications
1
Weights shown are nominal, and subject to variances.
2
Weights may vary due to different power supplies, IOMs, and differing calibrations between scales.
3
Weights may vary due to actual number and type of disk drives (SAS, SATA, SSD) installed.
Environmental requirements
* Temperature is de-rated by 3.6ºF (2ºC) for every 3,281 feet (1 km) above sea level.
Electrical requirements
Site wiring and power requirements
Each enclosure has two power supply modules for redundancy. If full redundancy is required, use a
separate power source for each module. The AC power supply unit in each power supply module is
auto-ranging and is automatically configured to an input voltage range from 88–264 VAC with an input
frequency of 47–63 Hz. The power supply modules meet standard voltage requirements for both U.S. and
international operation. The power supply modules use standard industrial wiring with line-to-neutral or
line-to-line power connections.
