Figure 4. Back View Of The 4220 Rack Enclosures - Dell PowerEdge 2420 Technical Manual

The wide and deep racks have the same design style as the standard 4220 and 4820 racks. In fact,
the deep racks look the same as the standard racks in a straight- on front or back exterior view, but
the extended depth can be seen in a side view. The additional 3 inches added on each side of the
wide rack are noticeable in the front and rear view of the rack, but from the side, the wide racks look
the same as the standard racks.
Dell rack enclosures have faster and easier access to the rear of rack with a single latch for both
doors. All of the 42U and 48U racks have two- piece side panels for easier removal and access to the
sides of the IT equipment and cables, as well as a split rear door design that includes a single latch
mechanism.
