Electrical Power Connections

The SmartEdge 600 chassis power architecture has connectors for a single
power zone.
Primary sources are designated as A sources; backup sources are B sources.
For a fully redundant power configuration, both sources must be connected.
Each power connection must be able to supply a minimum of 75 amperes. DC
power connections require copper wire of a size suitable for the installation in
accordance with the National Electrical Code (in the United States) or applicable
local jurisdiction (outside the United States) installation requirements. An
external fuse panel, either a stand-alone unit or incorporated in a DC power
supply system, or a circuit breaker panel is required for power-on and power-off
control. A DC-powered system uses –48 VDC power and is powered from a
fuse panel, which can be damaged by overloaded circuits.
Risk of equipment damage. Ensure that the fuses in the external fuse panel
are suitably rated for the installation in accordance with the National Electrical
Code (in the United States) or applicable local jurisdiction (outside the United
States) installation requirements.
1.3.1 AC Power Option
You can supply power to the SmartEdge 600 by means of an optional AC
Power Shelf (BMK 907 058/1). It requires a 200-240VAC power source. It has
two power modules (BMK 905 76/1) and a split power bus for redundancy.
Each power module is capable of delivering 2725 Watts.
The AC Power Shelf has a status port for use in monitoring warnings and errors.
