Oracle ZFS Storage ZS5-4 Power Supply

The two power supply slots are located on the right side of the Oracle ZFS Storage ZS5-4 controller (from the front of the controller) and are designated from right to left. The slots are accessible from the back of the controller. From the back of the controller, the left slot is designated as PS-0, and the right slot is PS-1.

1 PS 1

2 PS 0

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.
