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”
on page 208. 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.
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.
