To separate the removable cache card from the base card, do the following:

Important: All cards are sensitive to electrostatic discharge. See Working with electrostatic discharge-sensitive parts.
  1. Label both sides of the card before separating the cache card from the base card.
  2. Are you servicing a 2780 adapter or a 571E adapter?
    • If you are servicing a 2780 adapter, go to step 3.
    • If you are servicing a 571E adapter, go to step 9.
  3. Place the 2780 adapter on an ESD protective surface and orient it as shown in the following graphic. Note the position of the card handle.
  4. Remove the three screws A from the base card as shown.
    Tip: Note the thread differences of the screws for correct screw replacement. The two screws that were secured into the plastic handle have a different thread pattern from the machine thread screw that was removed from the front of the card.
