Here we’re going to take a deeper dive into S3800-24T4S and S3800-48T4S 1000BASE-T switches and compare them from the following aspects.

Gigabit Ethernet Switch

Port Attributes

Both S3800-24T4S and S3800-48T4S 1000BASE-T Gigabit Ethernet switches comply with 1000BASE-T standard and provide energy-saving networking solutions with Gigabit wire-speed performance. The former is equipped with 24 10/100/1000BASE-T Gigabit Ethernet ports and 4 10GbE SFP+ ports, while the latter comes with 48 10/100/1000BASE-T ports with 4 10GbE SFP+ uplinks. With the 10GbE SFP+ ports, you can connect them to 10GbE switches for higher speed networking. For both S3800-24T4S and S3800-48T4S 1000BASE-T switches, the 10/100/1000BASE-T copper ports can auto-negotiate 10Mbit/s, 100Mbit/s, 1000Mbit/s by requirements.

Basic Parameters

By checking the specific parameters of S3800-24T4S and S3800-48T4S 1000BASE-T Gigabit Ethernet switch, it is apparent to find many other differences between them. Since S3800-48T4S 48 port switch provides higher port density than S3800-24T4S 24 port switch, the former comes with larger switch fabric capacity and faster forwarding rate than the latter. Seen from the table below, it is obvious that the airflow direction of these two switches also differs from each other due to the different positions of the two built-in cooling fans.

Key Features and Benefits

Both S3800-24T4S and S3800-48T4S 1000BASE-T Gigabit Ethernet switches possess layer 2+ features such as LACP, QinQ, port monitoring and remote loop detecting. As fully managed switches, these two 1000BASE-T switches can support VLAN setup and various traffic classification as well as QoS flow control to guarantee the transmission of high priority packets. Besides, they both support DHCP snooping and IP source guard to effectively protect the user, equipment and network availability. The most significant difference between them is that S3800-24T4S is a stackabe switch while S3800-48T4S is not. S3800-24T4S 24 port switch provides true stacking of up to 4 switches, allowing you to configure, manage and troubleshoot multiple physical switches as a single unit. Therefore, it fits better for IP MAN convergence layer and large-scale enterprise zone as well as the core of the network layer.

FS S3800 Gigabit Ethernet Switch Deployment Scenario

FS S3800-24T4S and S3800-48T4S 1000BASE-T Gigabit Ethernet switches offer a broad range of options in setting up networking connections in home networking, SOHO and enterprises. Some typical deployments are demonstrated in the following to utilize FS S3800 1000BASE-T switches as enterprise backbone switch or server farm switch.

Enterprise Backbone Switch FS S3800-24T4S 24 port 1000BASE-T switch is a perfect choice for mixing Gigabit Ethernet and Fast Ethernet installations, which paves the way for any expected future expansion. The figure below shows FS S3800-24T4S switch operating as an enterprise backbone for a small LAN. It provides dedicated 1000 Mbps full-duplex connections to servers and 10/100 Mbps full-duplex connections between subscribers (IP phones/desktops here) and edge switches. All these connections are realized by cat5e/6/6a UTP cabling.
Enterprise Backbone Switch
Server Farm Switch Providing 24 Gigabit Ethernet ports, FS S3800-24T4S 1000BASE-T Gigabit Ethernet switch is ideal to be used as a server farm switch connecting to the servers and powerful desktops. As shown in the figure below, FS S3800-24T4S 24 port switch functions as a server farm switch between the server rack and the NAS storage. It’s linked to FS S3800-48T4S 48 port switch which woks as the backbone to set up connections between the router and edge switches. In this case, the connections attached to server farm switch and backbone switch are 1000BASE-T UTP cabling. And the downlinks between edge switches and end users (IP phones/desktops here) are accomplished via 10/100BASE-TX UTP cabling.
