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.
In 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 standard (4820) and wide (4820W) racks can hold up to four full-height or eight half-height units, while the deep (4820D) rack trays can accommodate twice as many.
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.
Deep racks (4820D) have expanded PDU trays in the back of the rack, which can be used for additional power management or for routing cables.
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 standard rack enclosure fits on two standard floor tiles, in a space two feet wide and four feet deep. The 4820W rack is slightly wider, and the 4820D rack is slightly deeper. Space planners can select the form factor that best meets data center needs.
Power management: An extensive portfolio of Dell PDUs and uninterruptible power supplies (UPSs) can be mixed and matched to meet your exact requirements.
Blanking panels: These panels can be used to help ensure proper airflow in the rack and enhance cooling efficiency. Plastic panels snap in place, while steel panels are attached with screws.
Toolless installation: Servers and other components can be installed quickly and easily with the Dell ReadyRails™ mounting interface for sliding and static rail kits.
