Power supplies
The NeXtScale n1200 DWC Enclosure Type 5468 supports six autoranging power supplies.
The power supplies get electrical power from a 200 - 240 V ac power source and convert the ac input into 12
V outputs. The power supplies are capable of autoranging within the input voltage range. There is one
common power domain for the enclosure that distributes power to each of the DWC tray and modules
through the system midplane.
