24-Port Gigabit Ethernet L2+ Switch, 24x Gigabit RJ45, with 4x 10Gb SFP+ Uplinks, Stackable Switch, Fanless

S3900-24T4S-R is an advanced Layer 2 Plus (Layer 3 Lite) Gigabit managed stackable switches with 24x 10/100/1000BASE-T and 4x 10Gb SFP+ uplinks, dual redundant power supplies and the fanless design guarantees the switch always working silently, and 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 maintaining simple management. 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.

Great to hear that even more warehouses are coming, but I must say that we are very pleased with how fast the delivery of the switches are.I am intended to replace all my old switches with FS Switches.

thank you for the years of support and Merry Christmas and a Happy New Year to you! FS Ethernet switches have some of the best ROI I have every experienced. Couple that with USA state-side phone tech support and an incredible CAPEX/OPEX combination. Just amazing!

Recieved FS S3900-24T4S-R Managed Switch several days ago,my customer started with one switch but will have me add a second one to "stack" with and create redundancy to the servers via dual 10Gbps fiber server LAGs. Find a switch that can equal all of this for $329, including free tech support via phone!
Our data transfer test (server-to-server) via SMB "copy-paste" averaged 1TB in 25 minutes.
FS has switches in all categories from 100Mbps to 400Gbps!
