About this task

If you plan to replace a power supply, keep the following requirements in mind.

  • You must have a replacement power supply that is supported for your appliance.

  • You have an ESD wristband, or you have taken other antistatic precautions.

    Note Do not mix PSUs of the different voltage types. Always replace like for like.
Before you begin

  • Review the details in the Recovery Guru to confirm that there is an issue with the power supply. Select Recheck from the Recovery Guru to ensure no other items must be addressed first.

  • Check that the amber Attention LED on the power supply is on, indicating that the power supply or its integrated fan has a fault. Contact technical support for assistance if both power supplies in the shelf have their amber Attention LEDs on.

  • Make sure you have the following:

    • A replacement power supply that is supported for your controller appliance model.

    • An ESD wristband, or you have taken other antistatic precautions.

    • Access to SANtricity System Manager:

      • From Grid Manager, select NODES > appliance node > SANtricity System Manager. Controller information is on the SANtricity System Manager tab.

      • Point a browser in your management station to the controller's domain name or IP address.

Prepare to replace a power supply.

Steps

  1. Collect support data for your storage array using SANtricity System Manager.

    1. Select Support > Support Center > Diagnostics.

    2. Select Collect Support Data.

    3. Click Collect.

      The file is saved in the Downloads folder for your browser with the name, support-data.7z.

  2. From SANtricity System Manager, determine which power supply has failed.

    You can find this information in the Details area of the Recovery Guru, or you can review the information displayed for the shelf.

    1. Select Hardware.

    2. Look at the power sam1130 ss hardware power icon maint e2800 and fan sam1130 ss hardware fan icon maint e2800 icons to the right of the Shelf drop-down lists to determine which shelf has the failed power supply.

      If a component has failed, either or both of these icons are red.

    3. When you find the shelf with a red icon, select Show back of shelf.

    4. Select either power supply.

    5. On the Power Supplies and Fans tabs, look at the statuses of the power-fan canisters, the power supplies, and the fans to determine which power supply must be replaced.

      A component with a Failed status must be replaced.

      Caution If the second power supply canister in the shelf does not have Optimal status, do not attempt to hot-swap the failed power supply. Instead, contact technical support for assistance.

  3. From the back of the storage array, look at the Attention LEDs to locate the power supply you need to remove.

    You must replace the power supply that has its Attention LED on.

Step 2: Remove failed power supply

Remove a failed power supply so you can replace it with a new one.

Steps

  1. Unpack the new power supply, and set it on a level surface near the drive shelf.

    Save all packing materials for use when returning the failed power supply.

  2. Turn off the power supply and disconnect the power cables:

    1. Turn off the power switch on the power supply.

    2. Open the power cord retainer, and then unplug the power cord from the power supply.

    3. Unplug the power cord from the power source.

  3. Squeeze the latch on the power supply cam handle, and then open the cam handle to fully release the power supply from the mid plane.

  4. Use the cam handle to slide the power supply out of the system.

    Caution When removing a power supply, always use two hands to support its weight.

Step 3: Install new power supply

Install a new power supply to replace the failed one.

Steps

  1. Make sure that the on/off switch of the new power supply is in the Off position.

  2. Using both hands, support and align the edges of the power supply with the opening in the system chassis, and then gently push the power supply into the chassis using the cam handle.

    The power supplies are keyed and can only be installed one way.

    Caution Do not use excessive force when sliding the power supply into the system; you can damage the connector.

  3. Close the cam handle so that the latch clicks into the locked position and the power supply is fully seated.

  4. Reconnect the power supply cabling:

    1. Reconnect the power cord to the power supply and the power source.

    2. Secure the power cord to the power supply using the power cord retainer.

  5. Turn on the power to the new power supply canister.

Step 4: Complete power supply replacement

Confirm that the new power supply is working correctly, gather support data, and resume normal operations.

Steps

  1. On the new power supply, check that the green Power LED is on and the amber Attention LED is OFF.

  2. From the Recovery Guru in SANtricity System Manager, select Recheck to ensure the problem has been resolved.

  3. If a failed power supply is still being reported, repeat the steps in Step 2: Remove failed power supply, and in Step 3: Install new power supply. If the problem continues to persist, contact technical support.

  4. Remove the antistatic protection.

  5. Collect support data for your storage array using SANtricity System Manager.

    1. Select Support > Support Center > Diagnostics.

    2. Select Collect Support Data.

    3. Click Collect.

      The file is saved in the Downloads folder for your browser with the name, support-data.7z.
