DIGITUS Industrial 8+4SFP+Port L2 managed Gigabit Ethernet POE Switch 8x GE RJ45 +4 SFP+ Port PoE

The DIGITUS DN-651161 is a managed industrial PoE switch with 8 Gigabit RJ45 ports and 4 SFP+ (10G) uplink ports. Designed for demanding network environments, it provides a 1.2 Tbps switching backplane, supports IEEE 802.3af/at PoE (up to 30 W per port), and operates from a 12–48 V DC input. The switch implements Layer 3 features, redundant network protocols and comprehensive traffic control to ensure reliable connectivity in industrial, manufacturing and critical infrastructure applications.

Advantages

The switch combines high backplane capacity with 10G uplinks and managed Layer 3 functionality to enable scalable, low-latency networks. It supports PoE on all RJ45 ports for powering devices, advanced redundancy protocols (STP/RSTP/MSTP, ERPS, VRRP) to minimise downtime, and traffic control features such as QoS (4 queues, WRR/SP scheduling), IGMP snooping and ACL/802.1X security for predictable performance and segmented networks. Management is available via WEB, CLI and SNMP, and monitoring tools include port mirroring, interface status monitoring and log management.

Suitable for

• Industrial Ethernet installations in factories and plants
• Industrial IoT deployments requiring PoE-powered sensors and cameras
• Critical infrastructure and transport networks needing redundancy and fast recovery
• Corporate or campus edge switches with 10G uplink requirements

How to use

Install the DN-651161 in a suitable industrial enclosure or rack and connect DC power within the specified 12–48 V range. Connect end devices to the Gigabit RJ45 PoE ports and uplink to core switches or servers using the SFP+ ports for 10G links. Use the web interface, CLI or SNMP to configure VLANs, QoS, PoE settings and redundancy protocols (STP/RSTP/MSTP, ERPS, VRRP). Monitor ports and logs to verify link status and troubleshoot as needed.

Recommendations

For reliable PoE delivery and optimal thermal performance, supply power from a DC source that meets the switch’s voltage range and ensure adequate ventilation. When deploying in critical networks, enable ERPS or VRRP and test failover behaviour to confirm recovery times meet operational requirements.
