The Cisco Catalyst 4500E series is a high-performance extension to the Cisco Catalyst 4500 series. The E-series is composed of the Cisco Catalyst 4500E series supervisor engines, E-series line cards, and E-series chassis, which are designed for a high-performance, mobile, and secure user experience with superior backward and forward compatibility, delivering exceptional investment protection for organizations of all sizes.
The Cisco Catalyst 4500E series also supports 10 Gigabit Ethernet line cards. The Cisco Catalyst 4500 12-port E-series 10 Gigabit Ethernet line card can be deployed for high-performance and high density 10 Gigabit Ethernet aggregation in the campus and in small to medium networks as a core switch. The Cisco Catalyst 4500E series 12-port 10 Gigabit Ethernet line card supports standard Small Form-Factor Pluggable Plus (SFP+) optics.
The Cisco Catalyst 4500E series 6-port 10 Gigabit Ethernet line card can be deployed for high-performance/low-density 10 Gigabit Ethernet aggregation in the campus, in small to medium networks as a core switch, or for high-performance wiring closets where additional 10 Gigabit Ethernet uplinks are required. The Cisco Catalyst 4500E series 6-port 10 Gigabit Ethernet line card supports standard X2 optics as well as the Cisco TwinGig modules.
The Cisco TwinGig converter module converts a single 10 Gigabit Ethernet X2 interface into two Gigabit Ethernet port slots, which can be populated with appropriate SFP optics, providing a total of 12 wire-speed Gigabit Ethernet ports if used in all six X2 interface slots. The flexibility provided by the TwinGig converter module enables customers to aggregate Gigabit Ethernet and 10 Gigabit Ethernet LAN access switches on a single line card. The ability to support either Gigabit Ethernet uplinks or 10 Gigabit Ethernet ports on a single line card further demonstrates the flexibility and the investment protection of the Cisco Catalyst 4500 series architecture.
