  2. How To Use This Presentation • Intended as an up-sell presentation from the 3750 to 4500 • Assumes that we also have to worry about the competition so need to set the 3750 baseline • Start by summarizing the key benefits/capabilities of the 3750 • The main presentation is only 20 slides. The rest is backup. • For each feature in the differentiation tables, you can click on the feature link to jump to a more detailed feature overview slide (you have to be in Slide mode). Then to return to the table, click on the link in the upper right corner of the feature overview slide. Please remove this slide when presenting

  4. Selecting a Wiring Closet SwitchKey Considerations Investment Protection • How long do I plan to keep this infrastructure in the network:3 years? 5 years+? • Can the Switch adapt to changes over the lifecycle expectation? High Availability—Minimize Network Disruptions • Does the switch have basic hardware resiliency capabilities:redundant power supplies, redundant fans, redundant supervisors? • Is non-stop traffic flow a must-have requirement under failure conditions? • Is maximizing up time and operational efficiency a key consideration? Scalability—Headroom for Growth • What future network services and applications should I account for? • Is there sufficient hardware resources (memory, TCAM size, power, switching capacity, etc.) available to support new services ?

  5. Selecting a Wiring Closet SwitchKey Considerations Convergence / IP Telephony Support • Can I support 15.4Watts/port on all 48 ports/slot simultaneously? • Can I support higher wattage as standards develop? • Is power supply and circuit redundancy a must-have for voice deployment? Security Services • Does it have dedicated hardware resources for line-rate security today and for tomorrow’s new security features? • Is securing my voice and data traffic a requirement? Manageability and Serviceability • Does the Switch provide features that simplify operations and lower TCO? A Compelling Price Point for the Value • Am I getting the best value for the price point?
