  40. Typical Data Center Breakout Network – 12-15% and growing HVAC Loss Servers & Storage Lighting The Network... a segment not to be ignored in the DC or the Converged Campus • Business case based approach to: consolidate, simplify, & renew to drive down footprint while capability increased • Like many we’re assessing our network equipment energy footprint. Findings show running on Nortel Network gear is more energy efficient than using the competition’s gear • Our energy efficiency calculator is aiding IT and Business teams understand and act on their Network energy footprint With the increasing role of “the Network” (virtualization, POE) – need to understand this impact ... An explosion in PoE is occurring

  41. The Challenge Do the math! • Use Energy Efficiency Calculator for FREE! • Input your own numbers Make the change! • Don’t wait, you can save NOW • Know your power tax • Reduce carbon footprint Do I replace inefficient? Yes! CAP & migrate Invest incrementally
