Exceedingly Strong and Secure

With a static load rating of 2,500 lbs and three sizes to choose from, the PowerEdge 4820 rack enclosure can provide the capacity you need to hold a full complement of data center equipment.

  • Wide (4820W): 750mm wide x 1070mm deep

With 6U more height than the Dell 4220 rack enclosure, the 4820 allows the maximum equipment density available in a Dell rack.

Categories: ,

Stabilizer feet, included with the rack, attach to the front and sides of each 4820 rack enclosure for increased stability. Interconnect kits are available to link adjacent rack enclosures.

Lockable side panels and front and rear doors provide security for data centers, remote offices, wiring closets, factory floors and other server environments.

Important PDU Mounting Features

n addition to U-space PDU mounting, the PowerEdge 4820 rack enclosure has specially designed trays inside the rear doors to easily mount vertical PDUs, without using any tools, so they won’t interfere with air circulation. The wide design of the 4820W moves the PDU trays even farther away from the rack’s frame, which reduces interference with installed equipment and cables.

Dell vertical-mount PDUs are available in a number of sizes and can be combined within a rack. The trays in the wide (4820W) racks can hold up to four full-height or eight half-height units,

A Bundle of Cable-Management Options


Removable “tail-bars” at the top and bottom of the back frame simplify power and cable routing. The bars can be reattached after the cables are in place.


Wide racks (4820W) move the side panels and PDU trays farther away from the equipment installed in the rack, allowing more room for cables in the sides and back.

Made to Stay Cool


The PowerEdge 4820 rack is designed to facilitate better airflow. The front and rear doors are 80 percent perforated, and flexible air dams help keep hot air from moving from the back to the front, alleviating a problem common in many racks. Dell’s wide rack enclosure employs extended air dams across the front to help ensure proper airflow containment. Available blanking panels can further manage airflow for unused U-space in the rack.

For hot-aisle/cold-aisle thermally efficient data center topologies, the 4820W rack is slightly wider. Space planners can select the form factor that best meets data center needs.
