Managed Customization
Features user management interfaces, including an industrial-like CLI, and WEB-based management, the DIS-300G-12SW is easy to manage and provides the security and controls to guard and shape your network needs.

Gigabit Connectivity with SFP slots
Designed with 8 x 100/1000BaseT ports and 4 x 100/1000Base SFP to suit a range of devices and network layouts.

Officially Certified
Certifications for vibration, shock, free-fall, and electromagnetic compatibility to maximise network uptime in a variety of deployment environments, including smart city surveillance, factory automation, and outdoor wireless networks.

Withstands Extreme Temperatures
Operates effortlessly in a range of industrial and harsh environments in temperatures from -40°C to +75°C, and can cold start from -40°C.

Strong Build
The tough housing has been created to keep your network protected and reliably rugged. That’s why every DIS-switch comes with a 5-year D-Link warranty.

High Availability
Rapid ring failover recovery time of < 20ms, with even faster PROFINET speeds available at project request.

Fast Deployment
For instant installation it features a snap-to-DIN-rail clip, and also supports wall mounting.

Fanless Design
With no moving parts inside to reduce downtime and maintenance call outs, the rugged housing has been optimised for the transfer of heat.

Discrete Size
Small but mighty. To make the most of cabinet space, it measures: 61 x 154 x 109 mm.
