Multi-Gigabit Switch for Growing Enterprise Campus Network

October 29, 2020

Demands Drive Changes in Enterprise Switches

The cloud-based services, Internet of Things (IoT), and the growth of wired and wireless end devices are pushing enterprise campus networks to accept a variety of access devices with multiple data rates like multi-gigabit Wi-Fi 6 (802.11ax) and Wi-Fi 5 (802.11ac) APs. Under such conditions, the enterprise network infrastructure must upgrade to meet the increasingly urgent needs and irresistible trends. And the demand for high-performance enterprise network switches supporting multiple rates becomes greater than ever. According to a report by Dell’Oro Group, the campus network market is moving beyond 1Gbps to 2.5Gbps/5Gbps in 2020 and the number of 2.5G/5G/10G multi-gigabit switch ports deployments will reach up to 25 million.

Multi-Gigabit Switches: Multiple Gigabits, Multiple Choices

For a long time, 1Gb has been the primary connectivity technology on most enterprise-class switches since it is adequate for almost all the traditional end-user devices such as desktops, printers, and wireless access points in enterprise campus networks. However, new technology and devices are developing and put great pressure on the gigabit network devices. For instance, 5G network cards, gaming computers, desktop computers, servers, network-attached storage (NAS) devices, or IEEE 802.11ac Wave 2 wireless access points are capable of 2.5 gigabit or 5 gigabit connectivity, and access points supporting 802.11ax standard can provide a 10GE uplink interface, which requires access switches to support data rate more than 1 gigabit. Furthermore, for 10GBASE-T network infrastructure, there is a limitation in the common cabling system as constructing a 10G network requires the newer Cat6a cabling instead of the Cat5e or Cat6, which may cost more and cause waste.

Luckily, under such a situation, some network switch vendors introduce multi-gigabit switches, which applies to the Nbase-T standards supporting 2.5G/5G rates, and fills the gap between 1G and 10G over the existing cables. By using the multi-rate Ethernet switches, network requirements can be achieved without upgrading the existing Cat5e or Cat6 cabling system, saving costs on the installation. At present, when we talk about multiple gigabits in enterprise campus networks, the speeds are referred to as 100M/1G/2.5G/5G/10G data rates.

FS Introduces New Flexible Multi-Gigabit Switch to Enterprise Network

FS introduced the new multi-gigabit S5860-24XB-U Ethernet switches to meet the needs for multiple speeds in enterprise networks. S5860-24XB-U switch enables the existing cabling infrastructure in an enterprise campus network environment to provide high bandwidth as well as high power over Ethernet connectivity.

The basic features of the S5860-24XB-U multi-gigabit PoE switch and its benefits are shown in the chart below.

S5860-24XB-U Switch Features Benefits
Multi-rate 100M/1G/2.5G/5G/10G with auto-sensing on a single port. Provides more options for end devices supporting multiple data rates and prepares for future use.
Multi-rate switch ports including 1000base-t RJ45, 1G/10G SFP+ and 10G/25G SFP28. Provides flexible port combination and meets different bandwidth upgrading requirements.
IEEE 802.3af/at/bt capable up to 90W Power over Ethernet. Compatible with the previous PoE standard-compliant devices and futureproof the next generation APs and powered devices.
IPv4/IPv6 dual stack design and abundant IPv6 routing protocols. Upgrades network to IPv6 network or build a new IPv6 network in a secure and reliable way.
Virtual Switch Unit (VSU) technology among multiple physical switches. Simplifies management and enables fault recovery within milliseconds.
1+1 redundant power supplies and 3 redundant smart fans. Ensures stable operation while reducing power consumption and noise.

Revive WLAN With Multi Rates

FS multi-gigabit managed switches optimize both wired and wireless network experience, enabling a diversity of end devices connected to the LAN in an improving bandwidth. S5860-24XB-U switches support multi-rate 24x 1G/2.5G/5G/10GBase-T auto-negotiation ports, which can connect Wi-Fi 6 standard wireless access points shipping with a 2.5Gbps or 5Gbps LAN connection. The switches deliver 2.5 or 5 times more bandwidth to the access applications without upgrading cables deployed. The use of multi-gigabit switches and Wi-Fi 6 access points makes it possible to access multi types of high rate IoT devices and help enterprise networks smoothly transit to the next generation.

Fulfill Power-Hungry Applications

PoE and PoE+ are the most commonly used standards in the current PoE systems with the maximum 15.4W/30W power for a single port. Once the power is above 30W, power cords have to be deployed to utilize the mains supply, which brings stress on the deployment cost, time, and maintenance. FS S5860-24XB-U multi-gigabit PoE switches comply with PoE (IEEE 802.3af), PoE+ (IEEE 802.3at), and PoE++ (IEEE 802.3bt). Except for the multiple PoE power types of 15.4W/30W/60W, it also supports UPoE (High Power over Ethernet) applications with up to 90W for one single port, which helps to enable the next-generation flexible workplaces. As long as your connected end devices support the standard, FS multi-gigabit PoE switches will continue to supply power for the end devices as well as transmit data at the highest speed on a given Ethernet cable system.

Scale Your Network Without Hassle

The flexible range of high-speed rate options enables multiple migration and more access devices from 1G to 2.5G, 5G or 10G as the end-users have the need. In the meantime, when new end devices and new switches are added in the network, Virtual Switch Unit (VSU) technology enables multiple FS S5860-24XB-U managed switches to act as a logical one via aggregation links. Single IP address, single CLI interface and auto-configuration deliver a diversity of users located in various areas with simple and flexible network management for optimizing admin experience as well as working productivity.
