DIGITUS Industrial 8+2-Port Gigabit L2 managed Ethernet POE Switch 8xGE RJ45 + 2 SFP Port IEEE802.3at (30W)

The DIGITUS DN-651157 is a managed L2 Gigabit Ethernet switch featuring 8 RJ45 ports and 2 SFP uplink ports in an IP40 metal housing. It is designed for industrial environments with an operating temperature range from -40 °C to 80 °C and includes a redundant 48–57 V DC power supply. Ports 1–4 provide PoE according to IEEE 802.3af/at with up to 30 W per port, making the unit suitable for powering devices such as cameras and wireless access points.

Advantages

This switch delivers Layer 2 management functions including VLANs, spanning tree protocols and fast recovery, link aggregation and flow control for improved network performance. It supports IGMP and MLD snooping to optimise multicast traffic, ACLs and QoS for traffic prioritisation, and offers ESD/EFT protection up to 6 kV. The device provides flexible management via SNMP and CLI and is mountable on a top-hat rail for easy installation.

Suitable for

• Industrial network installations
• IP camera surveillance systems
• Wireless access point backhaul and management
• Control and monitoring systems

How to use

Install the switch on a top-hat rail and connect the redundant DC power inputs within the 48–57 V range. Connect network devices to the RJ45 ports and SFP modules to the SFP slots as required. Configure Layer 2 settings, VLANs, QoS and security rules using the management interfaces (SNMP, CLI) to match your network design. Enable PoE on ports 1–4 when connecting compatible PoE devices and verify power budget and device requirements.

Recommendations

For reliable operation in industrial and outdoor-adjacent environments, ensure adequate ventilation around the IP40 housing, verify cable quality and grounding for ESD protection, and plan PoE power allocation per port to avoid exceeding available power capacity.
