Hot-swapping a power supply

You can hot-swap a failed power supply in a DS460C, DS224C, or DS212C disk shelf—nondisruptively replace a power supply in a system that is powered on and serving data (I/O is in progress).

Before you begin

All other components in the system—including the other power supply—must be functioning properly.

About this task


  1. Properly ground yourself.
  2. Unpack the new power supply and set it on a level surface near the shelf.
    Save all packing materials for use when returning the failed power supply.
  3. Physically identify the failed power supply from the system console warning message and the illuminated attention (amber) LED on the power supply.
  4. Turn off the failed power supply and disconnect the power cable:
    1. Turn off the power switch on the power supply.
    2. Open the power cord retainer and unplug the power cord from the power supply.
    3. Unplug the power cord from the power source.
  5. Press the orange latch on the power supply cam handle until it releases, and then open the cam handle to fully release the power supply from the mid plane.
    The following illustration is for a power supply used in a DS224C or DS212C disk shelf; however, the latch operates the same way for power supplies used in DS460C disk shelves:
  6. Use the cam handle to slide the power supply out of the disk shelf.
    If you have a DS224C or DS212C disk shelf, as you remove the power supply, a flap swings into place to block the empty bay, helping to maintain air flow and cooling.
    Note: When handling a power supply, always use two hands to support its weight.
  7. Make sure that the on/off switch of the new power supply is in the Off position.
  8. Using two hands, with the cam handle of the new power supply in the open position, support and align the edges of the new power supply with the opening in the disk shelf, and then firmly push the new power supply until it meets the mid plane.
    Attention: Do not use excessive force when sliding the power supply into the disk shelf; you might damage the connectors.
  9. Close the cam handle so that the latch clicks into the locked position and the power supply is fully seated.
  10. Reconnect the power supply cable and turn on the new power supply:
    1. Reconnect the power cord to the power source.
    2. Reconnect the power cord to the power supply and secure the power cord with the power cord retainer.
    3. Turn on the power switch.
      The power supply's power (green) LED and attention (amber) LED illuminate, and then within 40 seconds, the attention (amber) LED turns off.
  11. Return the failed part to NetApp, as described in the RMA instructions shipped with the kit.
