When a malfunctioning or broken robot enters the Repair Ward it is at first scanned by a CARSTIC robotic arm that another another CARSTIC could give it a red boot (a device that can instantly turn them off when needed) and turn it off. Then a third arm takes the robot to a waiting area or to the diagnostic room. When WALL-E accidentally damages the switch, the robotic arms get turned off causing the neon walls to open releasing the other reject bots.
