Four power supplies provide full redundancy. If a power supply in a redundant conguraon is removed

or fails, its redundant power supply takes over without interrupon. The power supply in PEM2 serves

as redundant power supply to the power supply in slot PEM0 and the power supply in PEM3 serves as

redundant power supply to the power supply in slot PEM1.
