S3900-48T6S-R is an advanced Layer 2 Plus (Layer 3 Lite) Gigabit managed stackable switch with 48x 10/100/1000BASE-T and 6x 10Gb SFP+ uplinks, dual redundant power supplies, and dual fans design ensures that the power supply of the switch will not be interrupted even if it fails, providing improved ease of use, highly secure business operations, improved sustainability, and a borderless network experience. The S3900 series switches support stacking capability with 1 and 10 Gigabit connectivity and advanced QoS to the network edge while supporting simple device management and network management via a Command-Line Interface (CLI) as well as an on-box web UI. The S3900 series are ideal Gigabit access and aggregation switches designed for SMB, enterprise, midmarket, and branch office networks to provide lower total cost of ownership.
