Cisco - Expansion module - 40 Gigabit LAN - for Catalyst 3850-24XS-E, 3850-24XS-S, 3850-24XU-E, 3850-24XU-S
The Cisco Catalyst 3850 Series is the advanced enterprise-class stackable Ethernet and Multigigabit Ethernet access and aggregation layer switches that provide full convergence between wired and wireless on a single platform. Cisco's Unified Access Data Plane (UADP) application-specific integrated circuit (ASIC) powers the switch and enables uniform wired-wireless policy enforcement, application visibility, flexibility and application optimization. This convergence is built on the resilience of the improved Cisco StackWise-480 technology. The Cisco Catalyst 3850 Series Switches support full IEEE 802.3at Power over Ethernet Plus (PoE+), Cisco Universal Power over Ethernet (Cisco UPOE), modular and field-replaceable network modules, RJ-45 and fiber-based downlink interfaces, and redundant fans and power supplies. With speeds that reach 10 Gbps, the Cisco Catalyst 3850 Multigigabit Ethernet Switches support various wireless speeds and standards (including 802.11ac Wave 2) on existing cabling infrastructure.
