8.1.1 Hot-plug power supply units
I A redundant power supply can be created by installing a second hot-
pluggable power supply unit (optional). If one power supply unit fails, the
other unit ensures operation can continue uninterrupted. The defective
power supply unit can be replaced without interrupting operation.
