  1. Insert a screw driver (flat) into the top of one of the side clips of the enclosure.

  2. Press down on the black clip.

  3. Twist the screw driver slightly until the clip "pops".

  4. Repeat for the other enclosure side.

  5. Once both clips are popped, gently pull out the front connector plate.
