D-Link DIS-300G-12SW 12-Port Industrial Gigabit Managed Switch
Industrial Connectivity With Room for the Real Installation The DIS-300G-12SW brings 8 × 10/100/1000BASE-T ports and 4 × 100/1000 Mbps SFP slots to demanding industrial networks. Its IP30-rated metal housing, fanless cooling and −40–75°C operating range suit control cabinets, factory networks and infrastructure sites where ordinary office equipment may not be the right fit. Data-only interfaces connect separately powered equipment without a PoE output. Managed VLANs, traffic priority, network redundancy and diagnostic tools help organise the installation and support fault finding. The external DC power supply is selected separately for the site, the required temperature range and any connected PoE load. Highlights Connections 8 × 10/100/1000BASE-T ports and 4 × 100/1000 Mbps SFP slots. No PoE output; endpoints require their own power. Compatible optical modules are selected separately.

Key Features
Connect the Equipment at the Edge
8 × 10/100/1000BASE-T ports and 4 × 100/1000 Mbps SFP slots. Copper links serve nearby equipment while the available optical slots extend the installation over a fibre route selected for the site. Select the cable and endpoint speed as part of the complete connection.
Build Around a Clear Power Design
The switch carries Ethernet data and does not provide PoE power to connected devices. Dual DC input paths allow an installation to use a suitable redundant power arrangement. Size the external supply for the switch and the cabinet conditions, and provide separate power for endpoints.
Keep the Cabinet Installation Practical
The IP30 metal enclosure and fanless design suit an appropriately protected industrial cabinet. The specified −40–75°C operating range gives more installation flexibility than a standard office switch. DIN-rail or wall mounting keeps the device close to the equipment it serves. The enclosure rating is not a weatherproof or waterproof rating; use the site enclosure required for the environment.
Keep Traffic Organised
VLANs separate services such as production, cameras and management. QoS and multicast controls help manage competing traffic on shared links, while access controls support a more deliberate security policy. These are configured functions, so the commissioning process should match the actual applications and network layout.
Support Recovery and Fault Finding
Ring protection, spanning tree and link aggregation provide options for a tested redundant topology. Management tools, logs and status indicators help locate an interrupted link or an abnormal power condition. Recovery performance depends on the design and configuration, rather than removing every possible interruption.
Extend the Link With the Right Media
The SFP interfaces use separately selected supported optical modules. Match fibre type, wavelengths, connector, distance and temperature rating at both ends.
