Installing an AC PSU

Note - When you install, hot-swap, or hot-add a new PSU, wait for 10-15 seconds for the appliance to recognize the PSU and determine its status. The PSU redundancy may not occur until discovery is complete. Wait until the new PSU is discovered and enabled before you remove the other PSU. The PSU status indicator turns green to signify that the PSU is functioning properly.

1. Follow the Safety Instructions.

2. Make sure that both PSUs are of the same type and have the same maximum output power.

   Note - The maximum output power (in Watts) is listed on the PSU label.

3. Slide the new PSU into the appliance until the PSU is fully seated, and the release latch snaps into place.

4. If you opened the hook-and-loop straps, close them to secure the system cables.

5. Connect the power cable to the PSU.

6. Make a loop and secure the power cable to the PSU using the retention strap.

7. Plug the power cable into a power outlet.
