DIGITUS priemyselný L2 Managed Gigabit Ethernet switch 16x RJ-45 + 2x SFP, 12–48V DC, 8000 MAC

The DIGITUS DN-651158 is an industrial L2 managed Gigabit Ethernet switch with 16 Gigabit RJ45 ports and 2 SFP uplink ports. Housed in an IP40 metal enclosure with redundant 12–48 V DC power input and operating range from -40 °C to 80 °C, the switch is intended for industrial environments, monitoring and wireless service applications that require reliable wired connectivity and uplink redundancy.

Advantages

The switch provides full Gigabit performance on 16 RJ45 ports plus 2 SFP ports, advanced Layer 2 management features including VLAN, link aggregation, spanning tree and fast recovery, and traffic optimisation via IGMP/MLD snooping and QoS. It supports extensive management options such as SNMP and CLI and includes ESD/EFT protection up to 6 kV. The IP40 metal housing, DIN-rail mounting and redundant DC power input make it suitable for industrial installations.

Suitable for

• Industrial network edge and control systems
• Video surveillance and camera system connections
• Wireless access point backhaul and monitoring systems
• Environments requiring wide temperature range and redundant DC power

Key specifications

• 16 x 10/100/1000 Mbit/s RJ45 ports
• 2 x 100/1000 Mbit/s SFP ports for fiber uplink
• Layer 2 management: VLAN, link aggregation, spanning tree
• IGMP and MLD snooping for multicast optimisation
• QoS and ACL support for traffic prioritisation and security
• Flow control (IEEE 802.3x) and 8000-entry MAC address table
• Redundant DC power input 12–48 V
• IP40 metal housing, DIN-rail mounting
• Operating temperature: -40 °C to 80 °C
• ESD & EFT protection up to 6 kV

How to use

Mount the switch on a DIN rail in a suitable IP40-rated cabinet or panel. Connect the DC power to the redundant 12–48 V inputs and verify proper power status. Use RJ45 ports for copper connections and SFP slots for fiber uplinks; configure port settings, VLANs, link aggregation, QoS and ACLs via SNMP, CLI or the supported management interface. Monitor link and device status and adjust multicast and flow-control settings to match the connected devices and traffic patterns.

Recommendations

For reliable operation in industrial or outdoor enclosures, ensure adequate ventilation and comply with the specified -40 °C to 80 °C temperature range. Use redundant DC power sources where continuous operation is required and enable spanning tree and link aggregation for resilient uplink topology. For camera systems, enable IGMP snooping to reduce multicast traffic on access ports.
