Features

Managed
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
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
Officially Certified

Certifications for vibration, shock, free-fall, NEMA‑TS2 Section 2, and electromagnetic compatibility to maximise network uptime in a variety of deployment environments, including smart city surveillance, factory automation, and outdoor wireless networks.

Extreme Temperatures
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
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
High Availability

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

PoE Support
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
Fast Deployment

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

Fanless Design
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.

Discreet Size
Discrete Size

Small but mighty. To make the most of cabinet space, it measures: 77 x 154 x 128 mm.
