AV DISTRIBUTION

Industrial Gigabit fiber access switch with cloud management
For industrial companies, infrastructure providers, and operators of critical systems, the LANCOM IGS-3128XF serves as a reliable distribution instance for internally networking other switches within the network. With its robust metal housing, flexible fiber-optic connectivity across all ports, and extended temperature tolerance, this cloud-ready industrial switch is ideally suited for demanding environments such as manufacturing, logistics, or energy supply. The 28-port Gigabit access switch features 24x 1G SFP ports – 4 of which can be used as combo ports (TP/SFP) – as well as 4x 10G SFP+ ports for uplinks and backbone connections. For flexible power supply options, the LANCOM IGS-3128XF comes with an internal AC power unit and an additional connector for external DC power sources. Its shallow housing depth allows for space-saving installation, particularly in compact distribution cabinets. With layer 3 lite functionality and support for the LANCOM Management Cloud (LMC), the LANCOM IGS-3128XF enables centralized and automated management of both the device and the entire network.

High performance on 28 ports
The LANCOM IGS-3128XF is equipped with 20x 1G SFP ports, 4x combo ports (TP/SFP), and 4x 10G SFP+ ports supporting transfer rates of up to 10 Gbps. The combo ports can be used flexibly as either copper (RJ45) or fiber-optic ports (SFP). With a data throughput of 128 Gbps on the backplane, it also offers full performance even under heavy load. This makes the industrial access switch the ideal central distribution instance in the network for connecting additional switches in modern network infrastructures.

Designed for industrial applications
Designed for use in severe frost or extreme heat (-20 °C to +55 °C), the LANCOM IGS-3128XF is optimally tailored to the requirements of the industrial and manufacturing sectors. Its metal housing provides enhanced resistance to bumps and vibration, while AC and DC inputs offer maximum flexibility in power supply options. The shallow housing depth of just 211 mm saves valuable space and allows for flexible installation – even in small network cabinets or confined environments. Compared to many standard switches with a depth of 300–400 mm, this design leaves ample room for effective cable management and optimal air circulation.

Cloud-managed LAN with port templates and Secure Terminal Access
With the LANCOM Management Cloud (LMC) and Cloud-managed LAN, the LANCOM IGS-3128XF offers quick and easy network integration as well as automatic provision of the configuration across locations with the a click of a mouse. Time-consuming individual device and switch port configurations are now a matter of the past. The targeted switch rollout via the LMC enables automatic VLAN assignment to switch ports including practical switch port profiles and therefore “zero-touch” assignment to the devices.

Secure Terminal Access provides access to the command line of the LANCOM switch ("CLI tunneling") directly from the LANCOM Management Cloud – encrypted and without leaving the cloud interface. Secure Terminal Access provides expert functions as well as extensive diagnostic and troubleshooting commands for the devices. Some highlights include: “trace” and “ping” commands for quick troubleshooting, access to low-level configuration parameters and detailed statistics of the LCOS SX operating system as well as secure remote access to third-party devices in the local network via the integrated SSH client.

Interference-free high-speed transmissions over distances of several kilometers
The LANCOM IGS-3128XF supports fiber-optic connectivity on all 28 ports, enabling reliable high-speed data transmission even across long distances. Link aggregation (LACP) allows multiple ports to be combined into a single logical channel, achieving a total transmission rate of up to 40 Gbps. As a result, this industrial access switch significantly boosts network performance and is ideal for organizations with extensive or distributed infrastructures. Another advantage: fiber-optics not only enhance installation flexibility but also effectively protect the network from electromagnetic interference – for example, when cables are laid parallel to power or machinery lines.

High reliability through redundant power supply
As a central distribution point for stable internal networking, the continuous availability of the LANCOM IGS-3128XF is essential. In addition to the integrated 100–240 V AC power supply, the industrial access switch also supports a 24–72 V DC power supply via an optional external power adapter (connection block), ensuring high operational reliability. If one power source fails, the other takes over – guaranteeing uninterrupted operation, even in critical infrastructure environments.

Configurable access control & secure remote management
The LANCOM IGS-3128XF stops rogue clients from gaining unauthorized access to the network. This is ensured by secured access control on all ports as per IEEE 802.1X (port-based, single, multi, and MAC-based) or by ACLs (access control lists). Thanks to secure communication protocols such as SSH, SSL, and SNMPv3, professional remote management of the network is possible. The switch also supports the TACACS+ protocol for authentication, authorization, and accounting. This optimized solution promises maximum security for multi-site network management and monitoring.

DHCP server functionality
As a DHCP server, the switch can independently and automatically assign IP addresses to clients. The LANCOM IGS-3128XF supports this basic layer 3 function and thus takes over the IP management of the connected network.

Static routing for efficient networks
The LANCOM IGS-3128XF supports the basic layer-3 function of static routing, shifting certain routing tasks from the router to the switch. The predefinition of network routes through one or more network segments enables faster data exchange, especially in the case of high internal data traffic, and reduces the load on the router. Freed-up router capacity is then additionally available for handling external data traffic. This increases the efficiency of the entire network.

IPv6 and IPv4 support
Thanks to its dual-stack implementation, the LANCOM IGS-3128XF can be used in pure IPv4, pure IPv6, or mixed networks. Numerous applications such as SSL, SSH, Telnet, or TFTP can thus also be run over IPv6 networks. IPv6 features such as stateless autoconfiguration, neighbor device discovery, and MLD snooping round out the IPv6 features.

Maximum future-proofing and digital sovereignty
As an established German manufacturer of IT network solutions, LANCOM stands for reliability and know-how. Software and hardware development as well as production take place primarily in Germany, as does the hosting of the network management. Special attention is given to providing trusted solutions with outstanding security features. Another important security characteristic of the products is that they are free from backdoors, as awarded by the German Federal Ministry of Economy with the quality seal “IT Security made in Germany”. All devices are always equipped with hardware that is dimensioned for the future. Even across product generations, updates to the LANCOM operating system family are available several times a year, free of charge. his guarantees a long service life while staying technically up to date, which represents a true protection of your investment. In addition, LANCOM infrastructures are easily scalable thanks to maximum compatibility.
