DIGITUS Industrial 8+4 SFP + Θυρών L3 managed Gigabit Ethernet Switch 8xGE RJ45 + 4 Θύρες SFP+

The DIGITUS DN-651160 is a managed industrial Gigabit Ethernet switch with 8 RJ-45 ports and 4 SFP+ (10G) uplink ports. Designed for industrial and infrastructure environments, it supports DC input voltages from 12 to 48 V, a 32,000-entry MAC address table and standards-compliant switching (IEEE 802.3x/802.1x/802.1Q). The metal housing meets IP40 protection and includes 4 kV lightning and surge protection. DIN‑rail (top-hat) mounting and redundant power input with reverse-polarity protection enable reliable, space-saving installation.

Advantages

The DN-651160 delivers Layer 2 and Layer 3 functionality with a high switching capacity and support for advanced features such as VLAN (IEEE 802.1Q), link aggregation (static and dynamic), QoS with COS/DSCP and four hardware queues, and multicast management (IGMP/MLD snooping). It provides redundancy protocols (STP/RSTP/MSTP, ERPS with <20 ms recovery, VRRP) and routing options (static routes, RIP, OSPF, OSPFv3). Management is available via Web GUI, CLI and SNMP, and monitoring features include port mirroring, interface status, logs and RMON/LLDP support.

Suitable for

• Industrial automation and control cabinets

How to use

Mount the DN-651160 on a DIN top-hat rail inside a control cabinet and connect DC power to the redundant power inputs observing correct polarity. Connect devices to the Gigabit RJ-45 ports and uplink aggregation to SFP+ ports as required. Configure VLANs, QoS, link aggregation and routing via the Web GUI or CLI, or integrate the switch into an SNMP management system for centralized monitoring. Use port mirroring and log functions to diagnose network issues.

Recommendations

Use shielded Ethernet cabling in electrically noisy environments; enable redundant power and frame/flow control (802.3X) for high-availability setups. Apply access control lists (ACL) and 802.1X to protect network access and configure QoS policies to prioritise critical control or SCADA traffic.
