2. Refined front-end perforation patterns more effectively prevent the buildup of dust around intake and exhaust

vents as well as within the system. This improvement in airflow and fan performance reduces power

consumption and enhances energy efficiency. Therefore, PowerEdge products can be further populated with

valuable hardware as the efficiency of cool air has increased throughout the box.

3. I/O ports were relocated from within the chassis to the rack ears. Implementing this design change enabled

more drive space within the box that customers can utilize for additional capabilities.

Thoughtful Design; From Start to Finish

Thoughtful design focuses on making conscious efforts to create positive environmental impacts, such as reusing

resources to minimize the global footprint. PowerEdge servers prioritize thoughtfulness over inconsequential

aesthetics to protect and preserve the environment and its future.

PowerEdge Thoughtful Achievements

1. Paint was removed from the front end of the server, hard drive carriers and the rear handles. The front end of

the server uses hemmed edges to conceal the metal edges, thereby eliminating any need for paint, enhancing

the chassis structure, as well as enabling IO components to relocate to the rack ear. Hard drive carriers use a

natural finish stainless steel, which reduces the volume of paint used on each server and improves signal

integrity. Lastly, the rear handles utilize a die cast process with a bead blast finish as an alternative to using

paint. These design changes allowed harmful paints to be removed from multiple processes, therefore

producing less air pollutants.
