This is HMI, also known as the Helioseismic and Magnetic Imager being wheeled into the cleanroom. Here we see it in its shipping container. Once it's inside the cleanroom a purge line will be attached to keep the instrument from getting contaminants, and also a ground strap will be attached because the instrument is electrically sensitive. That's a view of the HMI harness on the harness mock up and, as you look over there, you see the granite table and the instrument's being lowered down in a very level way in order to prevent binding of the four pins. There are six mounting feet. As you pan back you'll notice the spacecraft on your left and someone on the rolling staircase prepping the area for the electronics box. That's a view of HMI from the top. You can see the aperture on the front.
