6. Tighten the thumbscrews with a T-25 Torx screwdriver to secure the frame to the rack.
7. Repeat the procedure for the remaining frames.
NOTE: NOTE: Up to four 10U frames can be installed in a 42U rack. If you are installing more than one frame, install the
first frame in the bottom of the rack, and then install additional frames by moving up the rack with each subsequent
frame. Plan rack installation carefully because it is difficult to change the location of components after they are
installed.
