A plexi security cover was installed over the SPI Laser Chassis. Cover will be locked under normal operating conditions.
More pictures of the plexi-glass hatch. It secures to the chassis via screws and stand-offs, and has side openings. The box is merely trying to satisfy the "requires a tool to detach the fibers" criteria to make the system laser safe. The key will live in the control room lock box with all the other laser safety keys.
