Environmental Requirements

2.3.1

Electromagnetic Compatibility 

The following is required for all installations:

■

All AC mains and supply conductors to power distribution boxes for both the rack-
mounted array and the desktop array must be enclosed in a metal conduit or 
raceway when specified by local, national, or other applicable government codes 
and regulations. 

■

The supply conductors and power distribution boxes (or equivalent metal enclosure) 
must be grounded at both ends.

■

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.

Electrical and Power Specifications

The FC, SATA, and SATA SE arrays require two independent power sources. Each 
array has two power supply and two 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.

To ensure power redundancy, connect the two array power modules to two 

separate circuits (for example, one commercial circuit and one UPS).
