Prepare to replace power supply

You prepare to replace a power supply in a 24-drive controller shelf or drive shelf by collecting support data about your storage array and locating the failed component. The power supply is referred to as a power-fan canister in SANtricity System Manager.

Before you begin

About this task

This task describes how to prepare to replace a power supply for the following controller shelves:
  • E5724 controller shelf
  • DE224C drive shelf

You can replace a power supply while your storage array is powered on and performing host I/O operations, as long as the second power supply in the shelf has an Optimal status and the OK to remove field in the Details area of the Recovery Guru in SANtricity System Manager displays Yes.

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 and fan 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 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.
      Attention: 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.

    Power LED: If it is solid green, the power supply is functioning correctly. If it is Off, the power supply failed, the AC switch is turned off, the AC power cord is not properly installed, or the AC power cord input voltage is not within margin (there is a problem at the source end of the AC power cord).

    Attention LED: If it is solid amber, the power supply or its integrated fan has a fault.

After you finish

Go to Remove failed power supply.
