Product Highlights

S3900 Gigabit Stackable Switch Stacking Tutorial


Performance and Scalability

Up to 128Gbps/176Gbps switching capacity Delivers wire-speed switching performance on all Gigabit ports, taking full advantage of existing high-performance Gigabit CPEs, PCs,11n/ac Wi-Fi Applications etc, significantly improving the responsiveness of applications and file transfer times 4 built-in 10G SFP+ ports provide uplink flexibility, allowing the insertion of fiber or copper, Gigabit or 10G transceivers, to create up to 10 Gbps high-speed uplinks and stack links to enterprise or campus networks, reducing bottlenecks and increasing the performance of the access network

Reliability and Energy Efficiency

The design incorporate high energy efficiency in order to reduce the impact on the environment The Green Ethernet power-saving features significantly reduce the power consumption

Robust Multicast Control

IGMP snooping prevents the flooding of multicast traffic, multicast traffic is forwarded to only those ports associated with an IP multicast receiver

Superior Management

Industry-standard command-line interface (CLI), accessed through the console port or Telnet User-friendly web interface helps to quickly and simply configure switches

Continuous Availability

IEEE 802.1w Rapid Spanning Tree Protocol provides a loop-free network and redundant links IEEE 802.1s Multiple Spanning Tree Protocol runs STP per VLAN base, providing Layer 2 load sharing on redundant links up to 64 instances


Flexible Access Switches for Converged Enterprise Networks

Delivers the performance, flexibility, and scalability required for enterprise access deployment.Raising the bar with non-blocking performance and to create up to10 Gbps high-speed for uplinks or stacking.


High Performance Switch for Enterprise Networks

S3900-24F4S switch is Layer 2+ gigabit switch that provides fixed GE ports and 10 GE uplink ports. The physical stacking (up to 6 units) feature facilitates management for multiple switches with one single interface.
