To help organizations implement bestpractices for efficiency, Dell racks support a rangeof complementary accessories to enhance powermanagement, airflow, and component storageand mounting.To enable IT staff to mount Dell half-heightand full-height managed power distribution units(PDUs) without cables impeding airflow andequipment access, the Dell PowerEdge 4820 rackprovides a large distance between the back panelof the server and the PDU outlets. This rack alsosupports a wide range of options for PDU typesand form factors, and includes a tray for mountingPDUs at the rear of the rack as well as support forinstalling them in the U-spaces. The PDU tray hasbeen enhanced with additional mounting locationsfor PDUs and cable management accessories.Rack fan kits and blanking panels can helpensure proper airflow in the rack and enhancecooling efficiency. Plastic blanking panels in 1Uand 2U sizes are now available in addition to steelblanking panels in 1U, 2U, 3U, and 6U sizes. Theplastic blanking panels have a tool-less snap-indesign that enables quick, easy installation andremoval in the unused U-spaces in a square-holerack.
