Replacing a ZS3-4 Power Supply

Storage controllers are equipped with redundant hot-swappable power supplies. If a power supply fails and you do not have a replacement, leave the failed power supply installed to ensure proper air flow. A faulted power supply is indicated by an amber colored status LED. Use the following procedure to replace a ZS3-4 power supply.

1. Gain access to the rear of the storage controller where the faulted power supply is located.
2. If a cable management arm (CMA) is installed, press and hold the CMA release tab and rotate the arm out of the way.
   
3. Disconnect the power cord from the faulted power supply.
4. Grasp the power supply handle and press the release latch to remove the power supply.
   
5. Align the replacement power supply with the empty power supply chassis bay.
6. Slide the power supply into the bay until it is fully seated. The following figure shows the power supply.
   
7. Connect the power cord to the power supply.
8. Verify that the green AC Present status indicator is lit.
9. Close the CMA, inserting the CMA into the rear left rail bracket.
10. Go to the Maintenance > Hardware screen of the BUI. Click the right-arrow icon for the controller and then click PSU to verify that the online icon is green for the newly installed power supply.
11. If a fault does not self-clear, see Repairing Active Problems.
