SWITCH LANBERG ILFE-4P-1GE-1S-90 POE 1XBT 3XAT SFP/ETH DIN UNMANAGMENT FAST ETHERNETLightweight unmanaged industrial switch Lanberg ILFE-4P-1GE-1S-90 Industrial switches are an essential active device in any network structure - from automation and SCADA systems, through cable TV networks, to distributed IoT installations and surveillance. Lanbergs lightweight industrial switch series was designed for demanding working environments: a metal enclosure, passive cooling, and operating parameters that support stable operation across a wide ambient temperature range. The key advantages of this line include high PoE power (PoE+ / PoE++), redundant power input (you can connect 2 power sources), DIN-rail mounting, VLAN and EXTEND functions, automatic MDI/MDI-X, flow control, an intelligent PoE port cut-off function, and MAC auto-learning.In practice, this is a network switch built for distributed infrastructure: industry, street lighting infrastructure, outdoor CCTV monitoring, alarm systems, and both indoor and outdoor deployments where Ethernet data transmission and PoE power for end devices (cameras, recorders, access points, controllers, sensors) matter - often with higher power requirements.NOTE: The device power supply is included in the product set.Industrial switch ILFE-4P-1GE-1S-90 with a rich selection of portsThis switch is equipped with a port set optimized for CCTV/IoT installations: 4 x Fast Ethernet RJ45 PoE ports (10/100 Mb/s): 1× IEEE 802.3bt PoE++ (up to 90 W) + 3× IEEE 802.3af/802.3at PoE+. 1 x 1000BASE-T uplink (Gigabit Ethernet) - for traffic aggregation and connection to the network core / NVR / router. 1 x SFP slot (1000BASE-X) as a fiber uplink - optical parameters depend on the selected SFP module. Lanberg Gigabit Ethernet switches with PoE++ technologyPoE, PoE+ and PoE++ technology makes it possible to deliver both data and power to devices using a single Ethernet cable, without additional electrical infrastructure at the camera or access point. The technology based on 802.3af, 802.3at and 802.3bt standards allows powering peripheral devices with up to 120 W (90 W or 120 W depending on the model). A major benefit of the enhanced PoE standard is also high link quality and fast data transmission (up to 1 Gbps, depending on the model). Thanks to these capabilities, PoE is widely used in extensive surveillance networks. PoE+ and PoE++ enable real-time 4K camera streams while maintaining smooth performance.VLAN and EXTEND functionsVLAN helps with logical traffic separation (e.g., CCTV vs the rest of the network), improving order and limiting unwanted broadcast traffic. EXTEND mode was introduced for deployments where you need to ensure operation over a longer run - at the cost of speed. In practice, EXTEND can extend transmission and PoE powering up to 250 m on a single cable run (extend 250 m) in typical surveillance and distributed infrastructure deployments.An unmanaged switch that knows how to disconnect devicesIf too many devices are connected and the available PoE power reserve is exceeded, the switch will disconnect endpoints starting from the highest-numbered PoE ports down to the lowest until a safe power limit is restored. This makes it easy to plan for power spikes and define which devices are most critical and should stay online first.Intelligent switches with SFP module supportLanbergs lightweight industrial switches support different fiber types thanks to an integrated SFP slot. Optical transmission parameters depend on the selected SFP module. The switch also supports automatic MDI/MDIX, so crossover cables are not required, and it automatically detects and sets link speed and transmission mode.Unmanaged PoE switch with redundant power inputRedundant power input means a dual power feed to the switch (two independent power paths). If one source fails, the device automatically switches to the other - without user intervention. This solution provides higher security and network stability.Easy installation in 19" racks and on a DIN railInstallation is fast and hassle-free thanks to Plug & Play operation. MDI/MDIX auto-detection recognizes the cable type, eliminating the need for crossover wiring and automatically setting link speed and transmission mode. Reliable packet forwarding with CRC checking (store-and-forward) is essential in IP surveillance systems. A major advantage is DIN-rail mounting, which gives flexible installation options both inside RACK cabinets and outside them.Metal enclosure for durability and wide operating temperature rangeA robust metal enclosure improves durability and supports stable continuous operation. The recommended ambient operating range is -25 to 65°C, with 10-90% humidity. While the enclosure is not water- or dust-tight, installed inside an appropriate outdoor/industrial housing it will perform very well in demanding indoor and outdoor environments such as factories, production plants, and industrial halls.

For him, power is not a problem: a simple and functional LANBERG POE+ switch The PoE+ switch is an indispensable active device in any network structure that uses power transmission over structured cabling. The RSGE-24P-2GE-2S-250 is dedicated to all installations: home, business, low-current, monitoring, IP, VoIP, cable TV networks, and in particular finds use in alarm, fire and access control infrastructures. In addition to the primary function of the switch, i.e. handling Ethernet frame traffic between ports, it additionally provides power to each device in the PoE/PoE+ 802.3af and at standards. This makes it possible to supply up to 250 W total power to devices. And all this together with simultaneous data transmission to them. This saves resources, space and the time it would take to install a separate electrical and network installation. This is particularly important if the network is dispersed and its end devices do not have access to a power source, even more so if they are mounted outdoors. No-compromise solution - viable POE budget: 250 W The switch is equipped with a total of 28 ports, including 24 PoE+ (Gigabit Ethernet), 2 Uplink (Gigabit Ethernet) and 2 Uplink (SFP Gigabit) ports. Thoughtful design and attention to component quality provides the user with up to 250 W of total real power for end devices, which means that up to: 16 IEEE 802.3af devices (max. 15 W per port) or, 8 IEEE 802.3at devices (max. 30 W per port), The remaining 4 Uplink ports (2xGigabit Ethernet and 2xSFP Gigabit) operate independently and can operate simultaneously. They are dedicated to the exchange of data traffic between the 24 PoE+ ports and external devices. In the case of monitoring/control systems, this is particularly useful, as it allows the user to rip camera recordings to the DVR while simultaneously sharing the stream further (on the second port), e.g. on the local network or on the Internet. Intelligent POE port disconnection function It is not always entirely clear how a switch will behave when the available PoE budget is exceeded. There are several possibilities: the port that exceeds the budget will be disconnected, or a random port or the most recently connected port will be disconnected. In the last case, what will be their order after a power outage and its restoration when they are all plugged into the switch at the same time? Lanberg has introduced an innovative solution in the RS series switches which, through the simplicity of the operating principle, eliminates any doubt about the mechanics of the ports. When the PoE budget is exceeded (e.g. by a device connected to port 1), the switch will start disconnecting PoE ports starting from the highest numbering until the sum of loads exceeds the available budget; while keeping the operation of the other ports intact. Those that are disconnected will remain in this state until the PoE load decreases. The function is primarily dedicated to demanding applications that emphasize safety and business continuity, where some devices must operate without interruption regardless of the situation. In such cases, Lanberg switches will allow the user to protect sensitive devices by connecting them to the lowest numbered ports. EXTEND mode up to 250 meters Standard switches, in accordance with the standard, provide the ability to operate devices at a distance of up to 100 m on one cable section. However, sometimes, due to the extensive backbone and complex environment, a custom solution that goes beyond the standard is required when developing cabling and networking. In the case of monitoring solutions, this is a fairly common problem, most often resulting from too great a distance between the distribution device and the end device. Lanberg switches have a function that enables data transmission (max. 10 Mbps) and PoE+ power supply up to 250 m on one cable section. Simply switch the button to the PoE+ Extend 250m position on the case to provide extended operation for ports 1 ~ 24. The solution has been introduced for monitoring and IP systems as well as access control, especially if end devices are located outside without the possibility of installing additional network distribution points. 4 kV surge protection The switch itself, as well as the devices connected to it, are repeatedly exposed to various threats, including electric discharges that can flow through both power and network cables. Bearing in mind the safety of devices and their users, Lanberg equipped the switch with an integrated protection system against discharges, guaranteeing 4 kV protection for all ports, effectively reducing their damage due to rapid voltage increase. Under standard conditions, the network will continue to work without interruptions, the switch will continue to work without any interruptions, and the user gains the security of the device and infrastructure. Mounting kit included - ears up to 19" The RS series of switches is characterized not only by the quality of workmanship, ease of use, functionality of the device, but also complementarity in terms of assembly and supplied accessories, where possible. Lanberg has introduced a set of accessories for versatile assembly of its switches. The RSGE-24P-2GE-2S-250 includes mounting ears for cabinets 19 and a set of mounting screws (except M6). This enables a wider application and greater freedom of installation of the RS series switches.
