Main Features

• 24 Gigabit Ethernet Ports

The SWM281 has 24 × RJ45 Ethernet ports that support 10/100/1000 Mbps connections. This makes it good for connecting network devices through a single central managed switch.

• 4 Dedicated SFP Ports

Four SFP ports let the switch connect to fibre-optic networking equipment. Fibre connections are helpful when you need longer-distance network links or want to link parts of an infrastructure using fibre.

• L2+ Managed Networking

The SWM281 uses Layer 2 networking. Adds Layer 3 features. It supports VLANs, loop protection, static routing, and routing protocols, which gives network admins more control over network traffic.

• VLAN Support

VLANs allow a network to split into sections. This helps organizations separate types of traffic like office computers, security systems, servers, or industrial equipment.

• Advanced Routing

The SWM281 supports IPv4 and IPv6 routing and dynamic routing protocols like BGP, OSPF, RIP and EIGRP. This adds flexibility for bigger and more advanced network setups.

• Quality of Service

QoS features let network admins control traffic priorities using port priority, DSCP, 802.1p and TOS. Scheduling options include SP, WFQ and WRR.

• Network Security

The switch has network security features like authentication, MAC address filtering, RADIUS and TACACS+ support, preshared-key authentication and login-attempt blocking.

• Network Monitoring and Diagnostics

Tools like cable diagnostics, ping, traceroute, and nslookup help admins fix network connectivity issues. Find problems.

• Remote Management

The SWM281 supports Teltonika RMS, which allows firmware and configuration management for devices. Teltonika says the switch comes with 2 years of RMS Management.

• Industrial Protocol Support

For automation settings, the SWM281 supports PROFINET, MRP, and EtherNet/IP, helping it work in mixed industrial networking environments.

• 19-Inch Rack Installation

The SWM281 is built for installation in a standard 19-inch rack cabinet. Its rack-mount brackets make installation easy.

• Energy and utility networks
• Transportation infrastructure
• Smart city projects
• Retail networks
• Server rooms and network cabinets
• Data and communications infrastructure
• Industrial Ethernet networks
• Fibre-optic network uplinks
• Large-scale network deployments

Teltonika’s official material says the product is used for industrial and automation, energy and utilities, smart city, transportation, enterprise, and retail.

Technical Knowledge – What Does an L2+ Managed Switch Mean?

A standard network switch connects devices. Sends network traffic to the correct place. A managed switch gives the network admin control over how that traffic is handled.

The SWM281 goes past Layer 2 switching by adding Layer 3 features. In terms, this means the network admin can set up features such as:

• VLAN segmentation
• Traffic priorities
• Port isolation
• Port mirroring
• Static routing
• Dynamic routing
• Network access control
• Bandwidth control
• Loop protection
• Network diagnostics

This makes the SWM281 good for networks where performance, control, security and network organization matter.

Performance

The Teltonika SWM281 has 56 Gbps of blocking bandwidth and an 83.33 Mpps forwarding rate. It also supports a MAC address table of up to 8,000 entries and jumbo frames up to 10,000 bytes.

These specs make the switch good for network setups where many devices need to talk through a central switch.

Size & Weight

• Dimensions: 483 × 44 × 234 mm
• Weight: 1,853 g
• Rack Format: 19-inch rack
• Housing: Anodized aluminium housing and panels

The 44 mm height is a 1U rack format, so it fits in standard network cabinets where rack space is important. Teltonika says the SWM28 series has a 1U rack size.

Power

The SWM281 works with 100–240 VAC at 50/60 Hz. Uses a C14 power connector. Teltonika says the maximum power use is 20 W.
