Replacing a ZS5-2 Power Supply

---

Caution  -  If a power supply fails and you do not have a replacement available, do not remove the failed power supply. This maintains the proper air flow and prevents possible equipment damage.

---

Storage controllers are equipped with redundant, hot-swappable power supplies. Use the following procedure to replace a ZS5-2 power supply.

1. Identify the faulted power supply.

   • If you are not physically at the system, go to the Maintenance > Hardware section of the BUI, click the right-arrow icon for the controller, click PSU, and note the ID of the faulted power supply, which has an amber icon. To highlight the location of the power supply in the controller picture, click on the power supply ID. To view details about the faulted power supply, click its information icon and then click Active Problems.

   • If you are physically at the system, the amber Service Action Required indicator on the power supply should be lit.

   ---

   Note -  The fans of a failed power supply might still be spinning when the system is powered on. You can remove a power supply while the fans are still spinning.
