How to Remove a Power Supply

Power supplies are hot-swap capable. That is, the server does not need to be powered off to remove or replace a power supply. However, the two power supply configuration is the minimum configuration for the server (not recommended). The server cannot operate on one power supply.

Before You Begin

  1. Prepare the server for service. See How to Prepare for Service.
  2. Locate the power supply that you need to remove.

    If the power supply is in a fault state, the amber Service Action Required LED is on.

  3. To unlock the power supply, firmly squeeze the end of the release handle.

    The power supply release handle is located at the bottom of the power supply. The handle clicks when the locking mechanism is released.

  4. Pull the release handle out and to the right until the handle is fully extended.

    This action removes the pawl from the locking slot.

  5. Use the handle to pull the unit partially out of the slot.

    Pull the unit out far enough to grab it with your hands.

  6. Close the release handle by moving it to the left until it locks.
  7. To remove the power supply, slowly slide it out of the slot with one hand while supporting it with the other hand.

    Caution

    Caution - Airflow and temperature-related issues. Power supply slots contain an air vane that lowers when a power supply is removed from its slot. This device maintains proper airflow and cooling within the server.
