Managed Customization
Features user management interfaces, including an industrial-like CLI, and WEB-based management, the DIS-300G-8PSW is easy to manage and provides the security and controls to guard and shape your network needs.

Gigabit Connectivity with PoE and SFP slots
Designed with 4 x 100/1000BaseT PoE ports, 2 x 100/1000BaseT ports, and 2 x 100/1000BaseSFP slots 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.

PoE Support
With its 120 W PoE power budget, it’s been designed to supply data and PoE power to compliant devices, which removes the need for unnecessary plugs and cables and reduces deployment time and effort.

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: 77 x 154 x 128 mm.
