The S3900-24T4S-R is an L2+ managed stackable switch designed for SMBs, enterprises, midmarket, and branch office networks, offering a lower total cost of ownership. It features 24x 10/100/1000M RJ45 ports and 4x 10Gb SFP+ uplinks, delivering a switching capacity of 128 Gbps and a forwarding rate of 96 Mpps. Its dual redundant power supplies ensure uninterrupted power, even in case of failure, while the fanless design guarantees silent operation.
The switch supports stacking technology, which simplifies operations by interconnecting up to 8 switches that can be managed as a single logical device. It supports advanced features such as OSPF, Voice VLAN, robust QoS, Static Routing, and IPv6. Additionally, it offers simple device and network management through a Command-Line Interface (CLI) and an intuitive on-box web UI.
