S11, S31, and S32 Node base and expansion enclosures have two power supplies each, but the power supplies differ among the types of enclosures:
- In an S11 or S31 Node base enclosure, to accommodate the power requirements of the server modules, each power supply has two cores.
- In an S32 Node base enclosure, each power supply is part of a power and cooling module and has one core.
- In an expansion enclosure, each power supply has one core.
When an enclosure is operating normally, each power supply supplies half the power that the enclosure requires. However, if one power supply is unavailable, the enclosure can run on the other power supply alone.
