ZS5-4 Fan Module
The six fan module slots are at the front of the ZS5-4 controller and are set in two rows of three slots. The slots are designated from left to right. As pictured in the illustration below, the three front row slots are designated as: FM0, FM1, and FM2. The three back row slots are: FM3, FM4, and FM5.

ZS5-4 Power Supply
The two power supply slots are located on the right side of the controller (from the front of the server) 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.
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.

0 - 11 | DIMM slot numbers. Board labeling prepends a "D" to the slot number (for example: D0–D11). | B | Channel B slots: D0–D2 for memory buffer 0; D6–D8 for memory buffer 1. | A | Channel A slots: D3–D5 for memory buffer 0; D9–D11 for memory buffer 1. | C0 | Memory buffer 0. | C1 | Memory buffer 1. |
