Improving the Resource Efficiency and Resource Circulation of Products
In recent years, we have seen a rise in the risks that threaten the sustainability of companies and society in general, from environmental destruction due to resource shortages and excessive mining, to severe fluctuations in resource costs worldwide, and anxieties surrounding the supply of rare metals. Resource efficiency is thus taking on growing importance worldwide. Examples can be seen in the EU's designation of resource efficiency as a growth strategy and its establishment of the Resource Efficiency Flagship Initiative. We believe it is important for us to make efficient use of the resources in the ICT products that we provide to customers. We have engaged in a 3R design that draws on the principles of reduce, reuse, and recycle, and have developed our products with technology that is effective in reducing the amount of resources we use. We are also making efforts to improve resource efficiency and reduce our environmental burden by designing products to be lighter and smaller, using recycled plastics, reducing the number of parts, enhancing ease of disassembly, and improving recyclability. Our goal is to offer such products so that they provide even the customer with benefits, whether it be by making these products smaller, more lightweight, or designing them so they take up less space.

Improving the Resource Efficiency of New Products
In FY 2012, the Fujitsu Group created its own definition of resource efficiency, as the Group had previously not had a system that could comprehensively and quantitatively evaluate improvements in resource efficiency, and due to the fact that there were as of yet no public indices that could measure resource efficiency.
In FY 2018, we continued to use our indicators to evaluate products newly developed by Fujitsu *1, and worked to reduce product part quantities and reduce product size through smaller, thinner, and lighter parts and higher-density mountings.
*1 Products newly developed by Fujitsu:
Excludes products for which resource efficiency is determined by customer specifications or standards.
Achieved 25% Improvement in Resource Efficiency
By reducing the size and weight of our PCs, smartphones, mission critical x86 servers, POS tenant devices, and mobile phone radio base stations, and more, we were able to achieve an improvement in resource efficiency of 25%, against the 15% target value we set in the Fujitsu Group Environmental Action Plan (Stage VIII).
Working Toward Our Targets
To improve new product resource efficiency by at least 15%, Fujitsu will continue current initiatives, while expanding development of new lightweight, rigid materials and the use of recycled materials. We will also widely publicize the eco-friendliness of our products in order to expand sales.
Definition and Calculation of Resource Efficiency
Main Activities in FY 2018
The High-Performance SR-S352TR1/SR-S752TR1 Layer 2/Layer 3 Switch Combines Compact Size with Energy Conservation
The SR-S352TR1 and SR-S752TR1 is a 52-port (10G x 4 / 1G x 44 / SFP/SFP+x4) Layer 2/Layer 3 network switch that comes equipped with a 10G interface. The Layer 2 switch in particular qualifies as a Category A product under Japan's Energy Conservation Law.
The SR-S352TR1 and SR-S752TR1 are made with the latest ASIC switches, with their high performance and low power consumption, and as such require only one ASIC switch for features that previously required two ASIC switches. This, as well as the use of many components with low power consumption, allowed us to reduce power consumption during this product's use by 45% as compared to previous models).
All of the Ethernet ports, other than the SFP/SFP+ ports, also come with a power-saving Ethernet technology called Energy Efficient Ethernet (EEE) *2 that reduces power consumption during standby (not sending or receiving data) by 42% (compared to previous products). The product also comes with a technology that can limit the speed with which the cooling fans spin in multiple stages, depending on the temperature of the surrounding environment, helping save even more energy.
Previous models had the redundant power supply attached to the outside of the product (2U*2, including the body of the product). By reevaluating the product substrate and the structure of the components, however, we were able to redesign the product with high-density mounting, and install a hot swappable redundant power supply on the 19-inch rack, 1 U *3 case. In doing so, we were able to make the product smaller as a whole. The new model is also only 12% heavier than previous models, even with the redundant power supply now located within the main body, and is a step forward with regard to making the product more lightweight. The product is also now completely free of lead, as we have opted for lead-free soldering to mount the electronic components onto the printed circuit board.
We also improved cooling efficiency within the case, and incorporated a front intake air panel/rear exhaust air flow system in order to allow more efficient cooling when installed within the same rack as the server. This allowed us to equip the cooling system on the rack without wasting space, thus allowing us to make the product smaller in general.
*2 Compatible with IEEE802.3az, the IEEE standard specification.
