INTERIOR LABELS / TAGS
Inside the 5110 chassis, there is one “obvious label” near the switches at the top. Then there are several additional “hidden labels” deeper inside the chassis. For these other labels, one is behind the video display (along the main power cable), and the other is along the side of the video display components. Another label is inside the power supply.
Label near the top internal switches reads:
