  3. Remove the 15 screws (6-32x.31 Stainless Steel) that attach the System Power Board to the Mother board.

  4. Carefully lift the board up and remove the card from the System. Don't pull the board too far because there are still 3 cables attached to the card.

    Note: Interposer card(s) may come out. In this case, re-install the boards into the motherboard slots unit.
  5. Turn the board over and unplug the Genlock, Ethernet cable and Front panel keyboard cable. Refer to the drawing below (Bottom side) to locate the cables.
Note: After the system card is removed, you can also replace the System battery or the Solid-State memory. These items can be serviced without removing the System-Power board as described in other sections of this chapter.
