Remove circuit boards by pulling the top and bottom lever out simultaneously to disconnect the backplane connection.

When the card is disconnected from the backplane, slide the board out of the cage and store it in a safe place.

It is easier to remove a board next to an empty slot. If a board is sandwiched, especially the memory board (first slot) or display generator board (last slot), remove the adjacent board first.

When all boards have been removed, admire the backplane and blower.
