2.3 Environmental Requirements
Table 2-1 lists the environmental specifications for the SANnet II 200 SCSI array.
2.3.1 Electromagnetic Compatibility (EMC)
The following is required for all installations:
■
All AC mains and supply conductors to power distribution boxes for both the
rackmounted 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 of not more
than (+/–) 5 percent. The customer facilities must provide suitable surge protection.
2.4 Electrical and Power Specifications
All SANnet II 200 SCSI arrays require two independent power sources. Each array has
two power-supply-and-fan modules for redundancy.
Each SANnet II 200 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 to 264 VAC and 47 to 63 Hz. There is no need to make special
adjustments.
Each DC array requires two –48 VDC service outlets, and has a input voltage range of
–36 VDC to –72 VDC.
