■ The supplied arrays require voltages within minimum fluctuation.
■ The facilities voltage supplied by the customer must maintain a voltage with not
more than (+/–) 5 percent fluctuation. The customer facilities must provide
suitable surge protection.
2.4 Electrical and Power Specifications
Sun StorEdge 3510 and 3511 FC arrays require two independent power sources. Each
array has two power supply and fan modules for redundancy.
Each AC array requires two 115 VAC/15A or two 240 VAC service outlets. All AC
power supplies are autoranging and are automatically configured to a range of 90-
264 VAC and 47-63 Hz. There is no need to make special adjustments.
Each DC array requires two –48 VDC service outlets and has an input voltage range
of –36 VDC to –72 VDC.
Note – To ensure power redundancy, be sure to connect the two array power
modules to two separate circuits (for example, one commercial circuit and one UPS).
