FIGURE 2-13 Array Controller Tray Installed
The tray has mounting flanges on both sides with three mounting holes in them. The top and bottom holes are large enough to fit over the heads of the screws already in the cabinet rails used to mount the universal rails. If the tray was shipped with end caps (bezels) clipped on the tray mounting flanges, remove them before sliding the tray all the way in over the mounting screw heads.
To remove an end cap , place your thumb on the lower front face of the cap and reach your forefinger underneath to the back bottom edge of the cap, then pull the cap towards you and slightly upwards.
On the rear of the array tray, a flat metal tab on each side corner slides into a special mounting clip on the rear of each universal rail, securing the back of the array tray. This makes the use of rear mounting screws to secure the tray in the rail unnecessary, especially in locations where the rack and trays are not likely to be moved. For racks that will be moved or shipped, Sun recommends that you install M4 screws through the hole in the tab and into the corresponding threaded hole in the rail as shown in FIGURE
