D-Link DIS-300G series industrial gigabit switches

The DIS-300G series industrial gigabit switches, from D-Link, are ruggedised, high-performance devices designed specifically to support the rising demand for smart city applications, industrial automation and the growing adoption of Industry 4.0 techniques.

The industrial switches are claimed to feature superior environmental specifications compared to commercial network switches, making them suitable for smart city applications such as city-wide surveillance, universal outdoor wireless and two-way communication for autonomous vehicles. They can withstand wide temperature ranges from -40 to +75°C, as well as harsh vibrations and shocks, making them useful for outdoor deployment in kerbside compartments — whether in cold or tropical environments.

For government, local authorities, transport operators and the construction companies and system integrators that support them, the switches are designed to be simple to install and deliver a long service life with low maintenance requirements. Their hardened, robust design, combined with high-availability network features, enables the switches to perform their vital role in the network infrastructure without the need for air conditioning and vibration isolation enclosures.

For industrial purposes, particularly automation, the managed switches feature high EMI/EMC rejection enabling them to survive in high EMI environments such as welding bays and support fast network recovery under 20 ms to reduce downtime. They are also designed to enable greater and more granular configuration options for industrial and smart city applications. This includes remote monitoring of performance, fine-grained configuration of data flows and quality of service (QoS) to prioritise vital data.

The switches come in three variants — the DIS-300G-12SW, DIS-300G-8PSW and DIS-300G-14PSW — to give users flexibility around their requirements. They are available in PoE and non-PoE models.
