Replacing a 57B7 concurrent maintainable battery pack

Use this procedure to replace the concurrent maintainable battery pack on adapter type CCIN 57B7.

Attention: Before continuing with this procedure, determine that it is safe to replace the cache battery pack, see Maintaining the rechargeable battery on the 57B7, 57CF, 574E, and 572F/575C SAS adapters. It is safe to replace the cache battery pack when Yes is displayed next to Battery pack can be safely replaced. If the cache data present LED is flashing, do not replace the cache battery pack or the cache data is lost. See the feature comparison tables for PCIe and PCI-X cards and the following figures to determine whether your adapter has a cache data present LED and its location.

To replace a 57B7 concurrent maintainable battery pack, complete the following steps:

  1. Using the following illustration to locate the battery components, verify that the cache data present LED (C) is not flashing. If it is flashing, do not continue; return to Maintaining the rechargeable battery on the 57B7, 57CF, 574E, and 572F/575C SAS adapters.

    • (C) Cache present LED
  2. Move the cache battery lever (A) away from the connector to disengage the battery from the connector.
    Note: Hold the RAID auxiliary cache card with one hand to ensure it stays in the connector while you use the other hand to move the lever and remove the battery from the card.
  3. Continue to slide the cache battery pack out of the mounting guides and remove it from the controller.
    Note: Ensure that the cache battery pack is disconnected for at least 60 seconds before you connect the new battery. This duration is the minimum amount of time that is needed for the card to recognize that the battery has been replaced.
  4. Using the following illustration to locate the battery components, move the lever to the unlatched position (away from the connector).

  5. Slide the new cache battery pack into the mounting guides on the controller until it is seated in the battery connector.
  6. After the battery is seated in the connector, move the lever to the latched position to fully seat the battery into the connector.
  7. Restart the write cache of the adapter by completing the following steps:
    1. Navigate to the IBM SAS Disk Array Manager by using the steps in Using the Disk Array Manager.
    2. Select Diagnostics and Recovery > Controller Rechargeable Battery Maintenance > Start Adapter Cache Option.
