Unmanaged Switch Digitus DN-651120 4 Port Gigabit PoE

The DIGITUS Unmanaged Switch DN-651120 is a rugged industrial 4-port Gigabit PoE switch with one additional Gigabit uplink port. Designed for harsh environments, it provides four 10/100/1000Base-TX PoE ports that support IEEE 802.3af/at and deliver up to 30 W per port, plus one 10/100/1000Base-TX uplink port. The switch operates in a wide temperature range from -40°C to 80°C, has a switching capacity of 10 Gbit/s, a MAC address table of 4096 entries, and accepts a DC input of 48–57 V. Its compact, wall-mountable design and plug-and-play operation make it suitable for continuous use in transport, production, traffic and safety monitoring systems.

Advantages

The DN-651120 offers robust mechanical and thermal tolerance for industrial applications, integrated Power over Ethernet to power devices directly via the network cable, and Gigabit connectivity for high-bandwidth links. As an unmanaged switch it requires no configuration, enabling quick installation. The device’s wall-mountable form factor and support for IEEE 802.3at ensure compatibility with a wide range of PoE devices while maintaining constant availability under moisture, vibration and temperature stress.

Suitable for

• IP cameras and video surveillance systems
• Industrial automation and machine-to-machine networking
• Traffic control and intelligent transport systems
• Networked access points and VoIP phones in harsh environments

How to use

Mount the switch on a suitable flat surface or wall using the included brackets, connect the DC power supply within the specified 48–57 V range, and plug network devices into the PoE-capable ports. Use the uplink port to connect to a core switch or router. As an unmanaged device, the DN-651120 requires no configuration; connected PoE devices will receive power automatically if they comply with IEEE 802.3af/at.

Recommendations

Install the switch in a location protected from direct water ingress and ensure proper ventilation. Verify power supply capacity to provide sufficient PoE budget for all connected devices and use shielded cables where EMI or vibration is a concern. Regularly check connections and mounting hardware in vibration-prone installations.
