Then hold down the latches and slip the component rails out of the mounting rails. See Figure 30. latch mounting rail component rail Figure 30 Removing the Component Rail from the Mounting Rail (for Acer Altos 11000, 12000, or 21000) 2. Attach each mounting rail to the mounting bracket: i. Notice that the mounting rail consists of: · · a fixed outer piece that screws into the mounting bracket an inner sliding piece controlled by a steel ball gearing movement. This inner sliding piece is not detachable. 29 ii. Align the screw holes on the mounting bracket and the mounting rail. iii. Extend the inner sliding piece of the mounting rail. Align the two holes on the mounting rail with the holes on the mounting bracket. Fasten the mounting rail to the mounting bracket with two M5 screws. See Figure 31. mounting bracket Follow the path of the arrows when installing the mounting rail to the mounting bracket steps iv and v mounting rail step iii Left Right Figure 31 Aligning and Fastening the Mounting Rail to the Mounting Bracket (for Acer Altos 11000, 12000, or 21000) vi. Adjust the inner sliding piece to align the two holes on the other end of the mounting bracket with the mounting rail.
