As switch stacking, the premium feature of few network switches, evolves as a core competence of Ethernet switches in the market, vendors strives to release varies stackable switches and produce switch stacking tutorials for customers. This post will take FS S3900-48T4S 48-port stackable switch as an example to explore how to stack switches together..
Introduction to FS S3900 48T4S 48-port Stackable Switch
Port density and Scalability
S3900 48T4S 48-port gigabit switch comes with 48 downlink RJ45 ports that are triple speed copper ports connecting with end-devices and four 10Gbps SFP+ uplink ports that connect toward the core of the network. With 176Gbps switching capacity. This network switch delivers wire-speed switching performance on all Gigabit ports which support auto-negotiation for port speed and duplex mode. The 4 built-in 10G SFP+ ports provide uplink flexibility, allowing the insertion of fiber or copper, Gigabit or 10G transceivers. These 10Gbps SFP+ port can work as both uplinks and stacking links to servers or service provider, corporate, or campus networks, reducing bottlenecks and increasing the performance of the access network.
Reliability and Energy Efficiency
The dual power supply can ensure the effectiveness of mission-critical network. If one power supply fails for some reason, the other one will take over seamlessly to sustain the normal running of network. Moreover, the design of the S3900 48-port stackable switches incorporates high energy efficiency in order to reduce the impact on the environment. The fan is smart controlled by the traffic. When the switch runs busy, the fan inevitably generates much noise which, however, won’t cause distress. The Green Ethernet power-saving features can be translated into that, on an inactive link, the port moves into inactive mode and saves power while keeping the administrative status of the port up.
How to Stack 48-Port Gigabit Switch?
The S3900 48T4S 48-port network switch can allow up to six switch being stacked together, in which it excels S3800 series switches. Use DAC, AOC or transceiver modules plus fiber optic cable can simply join the switches together. Only the rightmost two SFP+ ports on the switch can be used to stack, and should be cross linked, as shown in the following picture.
How to Manage Switch Stacks Effectively?
Managing switch stacks is also not an easy work because there is a set of network switches in one stack unit. As for the S3900-48T4S stackable switch, an industry-standard command-line interface (CLI), accessed through the console port or Telnet*, provides a familiar web user interface and command set for users to manage the switch. Moreover, just one command and a reboot* can realize switch stacking, more convenient than common switch stacking. An embedded user-friendly web interface helps users to quickly check and manage the 48-port managed switch.
*Note 1: in stacking process, you need to pull and plug the console cable into each 48-port managed stackable switch repeatedly. By contrast, keep telnet cable connected with one switch is enough.
*Note 2: the one being restarted firstly is the stack master.
Conclusion
The S3900 48T4S 48-port stackable switch, born in this era where high speed network is badly needed, is an ideal Gigabit access switch for SMB, enterprise, and campus networks to boost productivity. And it is ideal for Internet Service Providers (ISPs) and Multiple System Operators (MSOs) to provide home users with triple-play services with up to Gigabit bandwidth.
Recently, many people have jumped on the bandwagon to use the 24-port Gigabit managed switch with advanced administrative controls. In particular, 24-port switch with PoE technology provides people with great convenience. However, the more power it sustains, the noisier it is. Have you been hassled by the endless noise or interrupted in your work? It is time to put an end to work frustration with fanless 24-port Gigabit switch.
What’s the Magic with Fanless 24-Port Gigabit Switch?
A Gigabit Ethernet switch without fan doesn’t mean that it does not have cooling system. Instead, it adopts a passive cooling system which achieves high level of natural convection and heat dissipation by a heat spreader or a heat sink to maximize the radiation and convection heat transfer modes. The passive cooling makes your switch dumb but not numb, as it still works efficiently. In a word, fanless switch is the most suitable in silent and energy-saving environments. Here introduce three distinctive fanless 24-port Gigabit switches.
Fanless 24-Port Gigabit Switch Recommendation

The entire network today has expanded and there emerge faster Ethernet switch like gigabit Ethernet switch and even 10gb switch which provide us with higher information switching speed. However fast they can forward the data packets, they still undergo complicated procedures. Now there is a way to simplify the data forwarding while maintaining the high forwarding speed. That is the MPLS network.
What Is MPLS Network?
MPLS stands for Multi-Protocol Label Switching. It is a system for fast packet switching and routing that provides the ability to target, route, forward, and exchange network traffic. In most cases, MPLS is regarded operating at Layer 2.5 as it enables data packets to be forwarded at layer 2 rather than layer 3. MPLS is a packet-labeling technique that can map IP addresses to simple fixed-length labels for different packet forwarding and packet switching techniques. MPLS can provide applications including VPNs (Virtual Private Networks), traffic engineering (TE) and Quality of Service (QoS). So we know that MPLS is a packet-labeling technique that prioritizes data, but how does it actually work?
How Does the MPLS Network Work?
In MPLS network, packets are directed through the network based on an assigned label. People tag some packets with certain markings. We can compare the packet to the shipping crate that ships something between two locations. If at every stop, the shipping company needs to open the box to figure out what it is and where it’s going to, it will cost a lot of time and energy. Now if we put the label outside indicating where the packet goes from and to, then whatever shipping company see it will know how to deal with it without opening it.
The basic component of MPLS network is label switching router (LSR). An ingress router with MPLS will label data packets (mail packages) on entry to the network (post office), so routers (mail workers) know exactly where the data is going to without having to open the package again and again. The transit router in the MPLS domain transmits the packet to the egress LER according to the label along the label switching path (LSP) consisting of a series of LSRs. Finally, the egress router that resides at the exit is responsible for stripping the label from the packet and forward it to the destination. In a word, transit router switch the data packet according to the attached label, while egress and ingress routers work for the transformation between MPLS and IP technology.
Advantages of MPLS Network
Here, some people may say “MPLS is indeed a good thing, but why should I bother to change to it as my current network runs well?”. This part will tell the advantage of using MPLS network.
First, regarding its cost, it is a cost-effective solution. Multiprotocol Layer Switching (MPLS) is an extremely scalable mechanism for high performance telecommunication networks. It allows for inter-connectivity growth of your network with minimal addition of hardware. An MPLS network uses communications via a cloud based network with each node connecting to the network providers MPLS cloud, which allows for adding new remote connections without the requirements of adding hardware at your primary site.
Second, let’s see its performance. It provides alternative network paths to improve up-time and reduce network congestion. It also allows for multiple traffic types to traverse the network, thus improving bandwidth utilization. It can also improve end user experience by allowing multiple classes of services to different types of traffic such as VOIP.
Third, one of the most notable benefits of MPLS is that it is applicable to any network layer protocol. It supports transport over Internet Protocol (IP), Ethernet, Asynchronous Transfer Mode (ATM) and frame relay; any of these protocols can be used to create an LSP.
Conclusion
In a nutshell, MPLS was originally put forward to improve forwarding speed. It decreases the forwarding overhead on the core routers. To make full use of it, you can go to the website www.fs.com and consult our experts. FS not only provides top-notch Ethernet switch but also first-class solutions.
