The 9C214-2 Power Supply
The 9C214-2 Power Supply, shown in Figure 1-1, is a 1000 watt, triple output
supply that accepts positive or negative 36–72 volt DC input. It provides power to
the three power busses within the SmartSwitch 9000 chassis. At least one power
supply must be installed; however, additional power supplies can be installed to
achieve redundancy. When two or more power supplies are properly installed,
the power supplies use a current sharing scheme where under all load conditions
each supply provides power equally.
