Replacing a 574E concurrent maintainable battery pack

Use this procedure to replace the concurrent maintainable battery pack on adapter type CCIN 574E.

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 data will be 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 574E 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 Forcing a rechargeable battery error.

    • (C) Cache data present LED
    • (D) Cache battery tab
    • (E) Cache battery tab
  2. Squeeze tab (D) against tab (E) to disengage the battery retaining tab, pull out the cache battery pack (B), and remove it from the controller.
    Important: Use caution when squeezing tabs because the plastic parts can be fragile.
    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.
  3. Install the new cache battery pack by reversing this procedure. Ensure that the replacement cache battery back is fully seated.
  4. Restart the write cache of the adapter by completing the following steps:
    1. Return to the Work with Resources containing Cache Battery Packs display and select the Start IOA cache. Press Enter.
    2. Ensure that you get the message Cache was started.
