These two control pannels, located in the Mechanical Workshop control the two independent dome hydraulic systems. Normally, observers don't need to interact with these boxes.

The box on the left controls the shutter hydraulic system. Normally, this system is controlled in the Control Room, but this panel allows the system to be controlled more flexibly.

The box on the right controls the dome drive hydraulic system. This system provides hydraulic pressure to push the four dome drive wheels against the rail.
