NOTE:

Before you attempt to replace a power supply:

  • Do not remove the PSU until you are ready to install the replacement
  • Never unplug or unseat both PSUs at the same time
  • Both PSUs in a controller or expander must be the same
  • Use only UL-approved power cords

Use this procedure to replace a failed AC power supply unit (PSU) on your HPE storage array or expansion shelf.

  1. Identify the power supply to replace. In the software, the right power supply is PSU1, and the left power supply is PSU2.
  2. Remove the power cord from the PSU.
  3. Push the power supply release lever to the left, grasp the handle, and pull out the power supply.
    1. Power supply LED
    2. Power supply release lever
    3. Power supply handle
  4. Insert the new PSU. Push in gently until you hear a click.
  5. Connect the power cord to the power supply.
  6. Secure the power cord in the strain relief strap that is attached to the power supply handle.

    2. Power supply handle

  7. Connect the power cord to the power source.

    Power is automatically restored to the PSU as soon as the cord is plugged in.
