Dell
The Dell power supplies utilize output Oring FETs to isolate the power supply from the 12V system
bus. If a single power supply fails its output Oring FET for that power supply will turn off removing
itself from the bus. Think of it as an electrical switch that turns off when the power supply fails.
5.1.1

Supported Voltages

Dell currently offers a power supply rated at 2360W 230V. With current sharing between power
supplies, total system redundant power is approximately 7080W in a 3+3 power supply configuration.
5.1.2

Redundancy

Power redundancy in the M1000e supports any necessary usage model, though the M1000e requires
three power supplies to power a fully populated system or six power supplies in a fully redundant
system.
AC redundancy is supported in the following configurations, each of which requires the power
supplies in slots 1, 2, and 3 to be connected to a different grid as compared to those in slots 4, 5,
and 6.
•
3+3
•
2+2
•
1+1
DC redundancy is supported in the following configurations, each with one extra power supply that
comes online if one of the existing power supplies fails:
