D-Link: with the “DIS family” you are on the safe side

The different D-Link DIS series industrial switch models are a good choice for any application, even in extreme environments due to operating conditions and temperature.
DIS Series means security: this is the first feature of these ranges of industrial switches by D-Link. There are four series: DIS-100G, DIS-200G (the last one), DIS-300G and DIS-700G, all united by reliability, construction solidity, certification for use even in extreme environments and NEMA-TS2 and EMC certification for vibration, shock and drop.
But let’s look at the individual products in detail. The DIS-100G series models are unmanaged Gigabit industrial switches that offer different mounting options and particularly compact dimensions, making them ideal for placement in outdoor lockers, on the street side. Equipped with snap hooks for guides, these products can be very quickly installed. The DIS-100G series consists of five models, with four, five or eight ports. The DIS-300G series instead offers three models managed by four or eight 100/1000BaseT PoE ports, with 4 100/1000BaseSFP slots (DIS-300G-12SW), with two additional 100/1000BaseT ports and two 100/1000BaseSFP slots (DIS- 300G-8PSW) and with 4 100/1000BaseSFP slots in addition to the two additional BaseTs (DIS-300G-14PSW).
The 300G and 700G series share high-availability network functions, guaranteeing the constant operation of the automation networks. An axcellent feature is the fast Failover, with a recovery time of around 20 ms and an even faster PROFINET recovery. The DIS-700G-28XS is a Layer 2+ managed Gigabit industrial switch with 24 100/1000BaseSFP ports, four 10G SFP+ slots and Layer 2+ managed customization. Also interesting in this model is the double redundant power supply.
Finally, the DIS-200G series, which offers two managed models, has recently been introduced: DIS-200G-12S is a 10 x 10/100/1000BaseT switch, with two additional SFP ports and RJ-45 Console port; DIS-200-12PS is instead an 8 x 10/100/1000BaseT, which offers in addition PoE+ on all these ports, and is completed by two additional 10/100/1000BaseT ports, two SFP ports and an RJ-45 connection. The applications of these products are many, from government offices to industrial environments up to the transportation sector. The fanless design and the possibility of mounting on a DIN rail or in-wall increase the durability and flexibility of the DIS-200G series models, which are also equipped with high-capacity 6 kV overvoltage protection on all copper ports to prevent damage caused by sudden changes in voltage or lightning.
All products of the DIS series – which together form a single, large family of industrial Gigabit switches – are characterized by a highly resistant IP30 class metal case that protects them from harsh environmental conditions, by the absence of internal moving parts, which significantly reduces the possibility of breakdowns or malfunctions, and by a heat dissipation system, designed to rapidly lower the operating temperature, if necessary. All models are also covered by a five-year warranty.
