Specifications
This appendix describes the physical and environmental specifications for the
StorageWorks RAID Array 200 Subsystem Family products.
Input Power Requirements
Input power requirements for a BA350-KB storage pedestal are determined by the
number and type of power units and system building block (SBB) devices.
Power Units
The enclosure can have a redundant power unit to ensure that a power unit failure
does not disable the unit. In most cases, battery backup units (BBUs) can be combined
with the pedestal power unit to provide extended system data integrity. Table A-1
contains the specifications for the BA350-KB power supply.
