Managed switch TELTONIKA SWM281 — 24x 1Gb RJ45, 4x 1Gb SFP

TELTONIKA SWM281 — 24x 1Gb RJ45, 4x 1Gb SFP is a managed Ethernet switch designed for edge and distribution layers of small to medium business and industrial networks. It provides 24 Gigabit copper ports for device connectivity and 4 Gigabit SFP slots for fiber uplinks, enabling flexible topology and reliable high‑speed links for LAN expansion and device aggregation. The switch offers centralized management features, VLAN segmentation and secure access controls to help maintain predictable network behaviour in office, retail or industrial environments.

Advantages

The switch combines a full set of Gigabit copper ports with SFP fiber uplink options, allowing seamless integration of copper and fiber segments. Centralized management and support for VLANs enable traffic segregation and easier network administration. Industrial-grade design considerations and hardware management features provide stable operation for edge deployments where reliability and controlled access are important.

Suitable for

• Expanding local area networks in offices and commercial premises
• Connecting access devices such as workstations, IP phones and wireless access points
• Aggregating edge devices and connecting to fiber backbone or upstream switches
• Retail and small data distribution points requiring VLAN segmentation and managed access

Key specifications

• Ports: 24 x 10/100/1000 Mbps RJ45 copper ports and 4 x 1 Gbps SFP slots
• Switching capacity: Gigabit non‑blocking performance for uplink and access aggregation
• Management: Managed switch with support for VLAN configuration and centralized management interfaces
• Layer features: Traffic segmentation via VLANs and access control capabilities
• Uplink options: SFP fiber modules supported for flexible topology and longer distance links
• Use case orientation: Designed for network edge and distribution with focus on reliability and predictable connectivity

How to use

Install the switch in a rack or on a shelf according to site requirements, connect power and ground per local electrical standards, and attach copper devices to the RJ45 ports. Insert compatible SFP modules into the SFP slots for fiber uplinks and connect fiber cables to upstream switches or backbone equipment. Use the management interface to configure VLANs, port settings and access control policies, and to monitor port status and link activity.

Usage recommendations

Place the switch in a controlled environment with adequate ventilation, apply firmware updates provided by the manufacturer, and use compatible SFP modules and high-quality category cabling to ensure stable Gigabit performance. Plan VLANs and link aggregation according to traffic patterns to optimise throughput and isolate critical services.
