Due to a series of complex factors like costs, lacking professional skills and uncertain future needs, the purchasing of network switches is usually tough, especially for small business network and home network. To fulfill these needs and help customers make a fast and right decision, FS provides S3900 series stackable switches including three models: S3900-24T4S, S3900-24F4S, and S3900-48T4S. All these switches are featured with rich Layer 2/2+ functions and can meet most enterprise campus, SMB, and even home networks’ demands for now and the future.
FS S3900 series switches are L2/L2+ managed switches that feature L3 routing, 10G speed, physical stacking and optional redundant external power unit, designed to meet the needs of the convergence or access layer. The switches come with 24 or 48 10/100/1000base-t ports and either 4 combo SFP/RJ45 ports or 4 additional 10G SFP+ uplink ports. Integrated with robust security and abundant management features, S3900 series switches offer a cost-effective solution for enterprise networks.

The S3900 series switches are equipped with BCM56150/BCM56151 chip. The BCM chip provides the industry-leading integration and performance, ensuring fast data processing and stabilized performance for our S3900 series switches. Also, the S3900 series switches have passed the Ixia test which provides an out-of-service benchmarking methodology that evaluates the performance of network devices using throughput, back-to-back frames, frame loss rate, and latency tests to ensure your network a higher performance.
The S3900 series switches highlight the stacking function. Up to six-switch stack enables users to expand their network capacity and simplify device management greatly. And the switch stack can still work even if there is a link or unit fails, which can effectively improve the stability of the whole network. The stacking capabilities of the S3900 series switches are ideal for limited spaced deployment (especially for small business) due to their flexibility and availability.
Fanless design is another highlight of S3900 series switches. For those who suffer from device noise at home, libraries, hospitals, or clinics, the S3900-24T4S fanless switch offers the best solution. It ensures the noiseless operation and increases the reliability and energy efficiency of the system.
The S3900 series switches support a complete lineup of L2 features, including link aggregation control protocol (LACP), STP/RSTP/MSTP, 802.1Q VLAN, port mirror, RSPAN, ERPS, DHCP snooping and so on. Advanced IGMP snooping and MLD Snooping can save cost and improve network efficiency on delivering multicast traffic by ensuring multicast traffic only reaches designated receivers without the need of an extra multicast router. Any more, the S3900 series switches also support L2+ feature—unicast routing, multicast routing and ARP, which can reduce the network traffic burden and helps the traffic for more efficient use.
The S3900 series switches support various IPv6 functions such as IPv4/IPv6 dual protocol stack, IPv6 ACL, IPv6 IGMP snooping, DHCP over IPv6, etc. All these functions can guarantee more convenient management and make your network ready for the future update.
S3900 series switches are user-friendly and easy to use. They support industry-standard CLI (command line interface) and web-based user interface management, which is friendly to professionals or newbies. Besides, by using CLI, the SNMP and Dual Image enable faster setup and configuration with less downtime.
All of our S3900 series switches are equipped with 4-year warranty hardware service and a lifetime free upgrade for the software of your switches. If you get into trouble while using our S3900 series switches, FS will provide you a comprehensive set service for your switches at any time you want.
FS understands the importance of providing great choices of rich enterprise-level features, competitive cost and less complexity. The S3900 series Gigabit managed switches offer different switch ports like combo port, RJ45 port, SFP and SFP+ port, which can adapt to diverse enterprise network needs.
The fanless design can make you work in a relatively quiet environment and the S3900-24T4S switch is mostly deployed for small business or places where silence is needed.
With 4 combo SFP/RJ45 ports and 4 10Gb SFP+ uplinks, the S3900-24F4S switch can achieve both fiber and copper transmission. It also provides more comprehensive security and faster speed for enterprise networks.
With 4 10G SFP+ ports, the S3900-48T4S switch facilitates an easy transition to 10G networking and stacking connection for secure enterprise access deployment and smooth wireless.
Is this switch available with DC power supplies? By Tim.Nowaczyk on October 2, 2019
The S3900-24T4S switch is not available with DC power supplies. It is equipped with 2 built-in AC power supplies by default. If you need the switches with DC power, FS S58 series switches(except the S5850-48T4Q) can provide the DC power modules. By FS on October 3, 2019
Hello. Does the equipment have Trunk Capabilities? If so does it support Dot1Q. Thank you and have a great day! By ITETINET.ITETINET on September 20, 2019
The S3900-24T4S switch supports Trunk and Dot1Q. You can get the detailed configuration guide in the Web Management Manual and CLI Reference Guide. By FS on September 23, 2019
I have two computers using a 10Gbe network card (Mellanox) with optics transceiver and of course fiber optic cable. Could I use this switch to connect these computers together to transfer files using SPF+ ports? In other words I’m interested in using this switch as a 4-port 10Gbe switch for the home. Will that work? (I'm confused by the "uplinks" description of it). Thanks By Daren.Jacobs on July 21, 2019
Thanks for your question. The S3900-24T4S switch can be used to connect computers and 10G network card (Mellanox) together by using SFP+ ports to transfer files. It can be used as a 4-port 10G switch for your home. We recommend the module #11552 to connect the terminal or connect the switch. By FS on July 22, 2019
I need to run a standard Linux user-mode application on this switch. Does the switch allow access to the Linux command line, or is the CLI the only thing that is available? There are other switches by FS that run Linux (ONIE), but those switches are too expensive for my particular application. By Just Curious on July 5, 2019
Thanks for your question. The S3900-24T4S switch can support CLI and web management, but it doesn't allow access to the Linux command line. Only our N-Series Switches can support Linux (ONIE). By FS on July 9, 2019
Are the SFP+ ports compatible with 10GBASE-T modules, such as FS P/N: SFP-10G-T? By Zan on May 9, 2019
Thanks for your question. The S3900-24T4S switch's SFP+ ports can be compatible with 10GBASE-T modules, such as FS P/N: SFP-10G-T. We recommend #66612. By FS on May 10, 2019
Does this switch work with a "C60 10G DWDM SFP+ 100GHz 80km Module, Cisco Compatible" transceiver? By Chinmay on April 22, 2019

Hello, S3900 series switches support port-based isolation. The detailed configuration guide, please kindly check the page 415 of the S3900 Series CLI Reference Guide. By FS on April 8, 2019
Hi, How can I start the User-web-interface (Ethernet) to make quickly and simply configurations? What is the default IP-Adress and the Login-data? I also like the answers to this question as I am about to buy this switch S3900-24T4S Can the 4 SFP+ be used in a common network together with the 24 RJ-45 ports since I need them for my NAS and 2 servers do not need the Uplinks and only need 1 switch By Volcano on April 4, 2019
Hello, the default IP adderess is 192.168.1.1. The login information is--username: admin, password: admin. More detailed configuration guide, please check the web and CLI manual in the “Download” section of the product page. Thanks! By FS on April 5, 2019

This is the smallest switch you do that has a 10G sfp uplink, yes? I would love to find a cheaper and smaller 8 port 1GbaseT with a 10G uplink. That’d be amazing with a 10G fiber aggregation, at least for what I am looking for By Derek on March 2, 2019
Yes, S3900-24T4S is the smallest switch with 10G SFP uplink, and 24 10/100/1000BASE-T ports which can meet the demand as you required. So we recommend the S3900-24T4S for you. Thanks! By FS on March 4, 2019
