Place the cover down so that it hangs over the rear of the server by about 13 mm (0.5 inches) and the side latches align with the slots in the sides of the chassis.
If the cover corners are not flush with the chassis, slide the cover towards the rear of the chassis until you can position the cover correctly.
Caution - If the top cover is not correctly positioned before you attempt to slide the cover toward the front of the chassis, the internal latch that is located on the underside of the cover might be damaged.
As you slide the cover toward the front of the server, watch the green release button. You will hear an audible click when the green release button pops up, indicating that the cover is locked.
