Each hutch door has a Door Control Box that is used to open and shut the door.

To open the door:
When a hutch door is shut, the Door Control Box shows two green lights that indicate that the door is closed and magnetically locked. If no experimentation is taking place, the door can be opened by pressing the red button labeled "Open." The door will then automatically open.

To shut the door:
When a hutch door is open, the Door Control Box shows two red lights that indicate that the door is open and magnetically unlocked. To shut the door, press and hold down the green button labeled "Close." Releasing the button will cause the door to stop and open again, so the button must be held down in order to close the door. Should anything get in the way of the door as it closes, simply release the green button and the door will re-open.
