Replacing a Storwize V7000 Gen2 power supply unit for a control enclosure

You can replace either of the two hot-swap redundant power supplies in an enclosure. These redundant power supplies operate in parallel, one continuing to power the enclosure if the other fails.

Before you begin

Attention:

  • Although many components are hot-swappable, they are intended to be used only when the component is not active (no I/O operations). If your system is powered on and processing I/O operations, go to the management GUI and follow the fix procedures. Initiating the replacement actions without the assistance of the fix procedures can result in loss of data or loss of access to data.

  • Be careful when you are replacing the hardware components that are located in the back of the system. Do not inadvertently disturb or remove any cables that you are not instructed to remove.

  • Ensure that you are aware of the procedures for handling static-sensitive devices before you replace the power supply.

Procedure

  1. Read the safety information in Preparing to remove and replace parts.
  2. Confirm that you know which power supply must be replaced. Go to Procedure: Identifying which enclosure or canister to service.
  3. Disconnect the power cord from the electrical outlet. Release the cable retention clip and disconnect the power cord from the power supply that you are replacing.
  4. Locate the orange release tab at the top edge of the power supply unit. Press the release tab gently until it stops.
  5. Using the handle, firmly pull the power supply out of the enclosure that is shown in Figure 1.

  6. Hold the new power supply so that the handle is fully extended.
  7. Slide the power supply into the enclosure until it stops. Push it firmly into position until it clicks.
  8. Connect the power cord to the power supply and to a properly grounded electrical outlet. Secure the cable with the cable retention clip on the rear of the power supply unit.
    Note: After the power cord is connected to the electrical outlet, make sure that the AC and DC power (green) LEDs are lit and the fault (amber) LED is off.
