The Teltonika SWM281 is a professional managed Ethernet switch engineered for high-density, high-throughput environments where PoE is not required. The switch is equipped with 24 Gigabit Ethernet ports (10/100/1000 Mbps, auto MDI/MDIX), yet it maintains fiber connectivity with 4 dedicated SFP ports for extended reach and resilient uplinks. It delivers a non-blocking switching capacity of 56 Gbps, a forwarding rate of 83.33 Mpps, along with a 512 KB packet buffer and an 8K-entry MAC address table. These capabilities ensure smooth handling of intense data flows, minimizing latency and maximizing throughput—ideal for CCTV, enterprise edge, and large-scale network deployments. Jumbo frames up to 10,000 bytes are also supported for enhanced efficiency in high-performance setups.

Running Teltonika’s TSW-OS, an OpenWrt-based operating system, the SWM281 provides extensive management and security tools to simplify network administration. It supports VLANs for traffic segmentation, link aggregation (LACP) to increase uplink throughput, port isolation and port mirroring for diagnostics, plus STP/RSTP for loop prevention. Advanced Quality of Service features such as 802.1p and DSCP prioritisation, bandwidth control and traffic shaping let you prioritise voice, video and critical M2M traffic. Network services include DHCP in server, client and static modes and static IPv4/IPv6 routing. Management is available via the web interface, SNMP v2/v3 and LLDP. Security includes 802.1X authentication, MAC filtering, RADIUS and TACACS+ support and access control lists to restrict unwanted traffic. Support for industrial protocols including PROFINET (Class B optional), EtherNet/IP and MRP makes the SWM281 suitable for automation systems. Two years of RMS remote management are included for centralized monitoring, firmware updates and configuration rollout.

The SWM281 is built for long-term professional use with a durable anodized aluminum chassis. It supports flexible installation with a rack mounting kit, ensuring easy integration into standard IT environments and professional network setups. Its compact and lightweight design makes the switch easy to install in standard network racks or cabinets, without taking up much space or adding unnecessary weight. The switch operates in ambient temperatures from 0 °C to 50 °C and tolerates relative humidity up to 90% non-condensing; the enclosure meets IP30 protection for indoor industrial environments. Power is supplied via an IEC C14 connector with a universal 100–240 VAC input range. Power consumption measures approximately 5.5 W at idle and up to 20 W at maximum load. Front-panel LEDs indicate power status and per-port link/activity. These characteristics make the SWM281 a dependable choice for CCTV, Wi-Fi and industrial edge deployments.
