Managed network switch TELTONIKA SWM281 — 24× Ethernet ports, 4× SFP ports, L2+

The TELTONIKA SWM281 is an L2+ managed network switch with 24 Ethernet ports and 4 SFP ports, designed for business and industrial LAN deployments. It supports centralized management and advanced Layer 2+ features such as VLAN segmentation, traffic prioritization and link aggregation, with flexible fiber uplink options through the SFP ports. The switch provides a compact and rack- or shelf-mountable solution for office networks, branch sites and edge locations requiring predictable connectivity and scalable port density.

Advantages

The switch combines 24 copper Ethernet ports with 4 SFP fiber ports to enable mixed copper and fiber topologies and flexible uplinks. L2+ capabilities facilitate VLAN isolation, QoS policies and efficient bandwidth utilization while centralized management simplifies configuration and monitoring across multiple devices. Link aggregation and redundancy features increase throughput and resilience for critical links. The device is engineered for continuous operation in small-to-medium network environments where deterministic switching behavior and administrative control are required.

Suitable for

• Office LANs and departmental networks
• Branch office connectivity and campus edge switching
• Industrial or commercial sites requiring fiber uplinks
• Network installations needing VLAN segmentation and QoS
• Environments where link aggregation and redundancy improve throughput

Key specifications

• Port count: 24 Ethernet ports plus 4 SFP fiber ports
• Switching mode: Layer 2+ (L2+), with VLAN support and basic Layer 3 features
• Traffic management: Quality of Service (QoS), traffic prioritization and rate limiting
• Link features: Link aggregation (LACP), port mirroring and redundancy support
• Management: Centralized management and configuration via web/CLI/management protocol (platform-dependent)
• Uplink options: SFP fiber ports for multimode or single-mode transceivers
• Form factor: Compact chassis suitable for rack or shelf mounting

How to use

Install the switch in a suitable location with proper ventilation and grounding. Connect Ethernet devices to the RJ45 ports and insert compatible SFP transceivers into the SFP slots for fiber uplinks. Use the management interface to configure VLANs, QoS policies, and link aggregation groups according to network design. Monitor port status and traffic counters via the management tools, and apply firmware updates and configuration backups as part of routine maintenance.

Usage recommendations

For optimal performance, plan VLAN and QoS settings before deployment, use appropriate SFP transceivers matched to fiber type and distance, and distribute aggregated links across separate physical uplinks for redundancy. Regularly back up configuration and update firmware to maintain security and stability.
