Replacing a 572B nonconcurrent maintainable battery pack

Use this procedure to replace the nonconcurrent maintainable battery pack on adapter type CCIN 572B.

1. Remove the controller from the system. See your system documentation for instructions.
2. Place the controller on a surface that is electrostatic-discharge protected.
3. Unplug the battery connector (B) from its connector on the adapter, squeezing the retaining latch while gently pulling on the plug. The plug connects to the board in only one way, so it cannot be inserted incorrectly during the replacement procedure.
   Note: Ensure that the cache battery pack is disconnected for at least 60 seconds before connecting the new battery. This duration is the minimum amount of time needed for the adapter to recognize that the battery has been replaced.
   Figure 1. Removing the cache battery

   

   • (A) Cache battery pack
   • (B) Battery connector
   • (C) Plastic rivet
   • (D) Plastic pin
4. Locate the two plastic rivets (C) that hold the cache battery pack in place. From the back of the adapter, remove the two pins (D) that are inserted inside of the rivets.
5. Release the rivets (C) that secure the battery assembly to the adapter. Press the rivets through the back of the adapter and remove the battery pack (A) from the adapter. If the rivets (C) cannot be pressed through the back of the adapter, follow these steps to press out the rivets with a ballpoint pen:
   1. Locate a retractable ballpoint pen.
      Note: A medium-sized retractable ballpoint pen is preferred, or an equivalent item with a small opening can be used. The small opening must be large enough so that the pen (or equivalent) can go around the tip of the rivet, but small enough that it does not slide over the rivet and contact the battery assembly bracket.
   2. Slide the card off the edge of the work area enough so rivet (C) can be pressed out of the back of the adapter.
   3. Hold the pen with the ballpoint retracted, place the pen on top of rivet (C), and gently press straight down until rivet (C) presses out.
   4. Repeat steps 5.b and 5.c for the other rivet (C).
   5. Remove the cache battery pack (A) from the adapter.
   6. Turn the adapter over and press the rivets (C) back into the adapter.
6. Install the new battery pack. (A) onto the press rivets (C) of the adapter.
7. Reinsert the pins (D) into the rivets from the back of the adapter.
8. Connect the cache battery pack connector (B) to the adapter. The plug connects to the adapter in only one way, so it cannot be inserted incorrectly.
9. Reinstall the adapter.
