Cisco Catalyst 4500-X Series provides scalable, fixed-campus aggregation solutions in space-constrained environments. The solution provides flexibility to build desired port density through two versions of base switches along with optional network module, providing line-rate 10GE capability. Both the 32-port and 16-port versions can be configured with optional network modules and offer similar features. The Small Form-Factor Pluggable Plus (SFP+) interface supports both 10 Gigabit Ethernet and 1 Gigabit Ethernet ports, allowing customers to use their investment in 1 Gigabit Ethernet SFP and upgrade to 10 Gigabit Ethernet when business demands change, without having to do a comprehensive upgrade of the existing deployment. The uplink module is hot swappable. Can rapidly increase network capacity with minimal effort Cascade to other network devices through the uplink port to expand your local area network Layer 2 switch provides a complete lineup of features including IGMP snooping, port mirroring, and spanning tree Rack-mountable form factor for added reliability and dependability Management capability allows maximum efficiency and with unrestricted control Optimize the performance of business networks with 10 Gigabit Ethernet connectivity Supports optical fiber cable to span longer distances and provided high data transmission rates between servers and network components
