Set the cover down so that it hangs over the rear of the server by about an inch (25 mm) and the side latches align with the cutouts in the chassis.
If the cover is not fully down and flush with the chassis, slide the cover towards the rear of the chassis to position the cover in the correct position.
Note - If the top cover is not correctly positioned before attempting to latch the cover, 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.
