Replacing a concurrently maintainable battery pack

Use this procedure to replace a battery pack that is concurrently maintainable.

Note: If your system enclosure does not allow concurrent access to the battery, refer to Replacing a nonconcurrently maintainable battery pack to replace the battery pack.
Determine whether it is safe to replace the cache battery pack by referring to Displaying rechargeable battery information. It is safe to replace the cache battery pack when the Battery Information screen displays Yes at the entry "Battery pack can be safely replaced."
  1. Remove the controller from the system. See your system documentation for instructions.
  2. Place the controller on an ESD protected surface.
