Oracle ZFS Storage ZS11-2 Power Supply

The two power supplies are located on the right side of the controller (from the front of the controller) and are designated from top to bottom. The power supplies are accessible from the back of the controller. As indicated in the following drawing, the top designation is PS 1 and the bottom designation is PS 0.

1 Power supply 0

2 Power supply 1

The two power supplies ensure redundancy by allowing the controller to operate when one of the power supplies fails. However, when the controller is operating on one power supply, redundancy no longer exists, and the risk for an unexpected shut down and a loss of data is high. When a power supply or any component that is part of a redundant configuration fails, replace it immediately.
