Managed Gigabit Ethernet switch Digitus DN-651145 8 portů L2

The Managed Gigabit Ethernet Switch Digitus DN-651145 is an industrial L2 switch with 8 x 10/100/1000 Mbps RJ45 ports and 4 Gigabit combo ports. Ports 1–8 support PoE with up to 30 W per port. The switch complies with IEEE 802.3 family standards, provides a switching capacity of 24 Gbit/s, accepts DC input voltage in the 12–55 V range, and is designed for fanless, low-power operation with extended temperature tolerance (-40 °C to 75 °C). The unit includes lightning and electrostatic protection and is intended for industrial broadband data transmission scenarios such as intelligent transportation, telecommunications, security and surveillance, finance and customs.

Advantages

The DN-651145 offers layer‑2 managed features including QoS, VLANs, security policies and both static and dynamic link aggregation (LACP). It supports multiple redundancy and protection mechanisms — ring network mode with one‑click setup, STP/RSTP/MSTP for two‑layer link protection and one‑click storm suppression — improving link reliability and minimizing downtime. Management is flexible: Console, Telnet, SSH and web GUI are supported, and firmware/configuration files can be transferred via TFTP. The chassis uses an aluminum heat-conduction design for passive cooling and compact, easy mounting.

Suitable for

• Industrial Ethernet networks in transportation systems

How to use

Mount the switch in an appropriate industrial cabinet or DIN-rail location according to installation guidelines. Connect DC power (12–55 V) and verify LED indicators for power and link status. Attach Ethernet devices to the RJ45 ports and uplink to the network via combo ports as required. Configure network settings through the web GUI, Console, Telnet or SSH; create VLANs, QoS rules and security policies as needed. If using PoE devices, connect them to ports 1–8 and confirm power delivery per port.

Recommendations

Use ring mode or STP/RSTP/MSTP for redundancy in critical networks, and enable storm suppression when deploying many multicast or broadcast devices. Ensure power supply matches the DC input range and account for PoE power budgets when planning connected devices.
