In the two-power supply configuration, the server is by default configured for 1 + 1 power redundancy. The power supply 1 (blue) and
power supply 2 (orange) are supported horizontally for redundancy.
Four-power supply configurationFour-power supply configuration
The server supports the following power supply redundancy modes in the four-power supply configuration:
2 + 2 Redundancy—The server will continue to operate if two power supplies fail or if one power supply feed loses power.
3 + 1 Redundancy—The server will continue to operate if a single power supply fails. The server will initiate operating system shutdown
if two power supplies fail. No power redundancy is possible.
4 + 0 Redundancy—There is no power supply redundancy. The server consumes more power than what redundancy can supply, and will
initiate operating system shutdown if one or more power supplies fail.
In a four-power supply configuration, the server is by default configured for 2 + 2 power redundancy. The power supplies 1–2 (orange), and
power supplies 3–4 (blue) are supported horizontally for redundancy.
