Remove a PSU

Access this component directly from the front of the server. You might need to remove a PSU to replace it or to access the release latch for the front indicator module (FIM).

Before You Begin

  1. Prepare the server for hot service. See Prepare the Server for Hot Service.

    Alternatively, to prepare the server for cold service, see Prepare the Server for Cold Service.

  2. Identify the power supply by its position and designation or, if it has failed, by its steady on Service Action Required indicator.

    A power supply in a fault state has a lit amber-color Service Action Required indicator.

    Note -  To access, the FIM release latch, you need to remove the topmost PSU.

  3. To unlock the power supply lever, squeeze together the two green release latches at the end of the lever.

    This action is accompanied by an click sound.

  4. To disengage the power supply from its internal connector, rotate the lever to the left.


    Caution  -  Pinch point. When operating the lever, keep your fingers clear of the hinged end of the lever.

    The pawl at the hinged end of the lever engages the sidewall of the server and provides the pivot point for the leverage necessary to disengage the power supply. This action leaves the power supply extending partially from its slot.

  5. To remove the power supply, use two hands to slowly slide it completely out of the server.
