Lenovo Flex System Enterprise Chassis -48V DC 2500W Power Module
Part Number: 00FJ635
The Flex System Enterprise Chassis supports up to six auto ranging power supplies.
The power supplies get electrical power from either a 200 to 240 V ac power source, a 240 to 380 V dc power source, or a -48 to -60 V dc power source depending on the type of power supply. Both ac and dc-powered supplies convert the power source into 12 V dc and 3.3 V dc outputs to the system midplane. The power supplies are capable of autoranging within the input voltage range. There is one common power domain for the chassis that distributes dc power to each of the nodes and modules through the system midplane.
Power supply redundancy is achieved when there is one more power supply available than is needed to provide full power to all chassis components. Power source redundancy is achieved by distributing the power cord connections between independent supply circuits.
