To install or replace the drives in the AKiTiO Thunder2 Quad, it's easiest if you place the device at the edge of the table so that the front protrudes over the edge.
The lock switch is located in the center underneath the front panel. Slide and hold the lock switch and then push the inner chassis from the back to expose the front panel.
Pull the top part of the front panel away from the enclosure and lift it up to remove it.
You can now unfasten the thumbscrews for those trays where you would like to install or replace the drives. Once done, replace the front panel, slide and hold the lock switch and push the inner chassis back into the enclosure.
