Quality and Quantity of Replacement Parts We have a procurement and production system that supports the EOSL maintenance business, maintaining the ability to procure and stock EOSL parts as well as quality inspection capabilities. We stock a sufficient quantity and quality of maintenance replacement parts and will generously deploy them in preparation for hardware failures covered under maintenance contracts.

ISO 9001 Certification and ISO 27001 Certification We have implemented management systems for ISO 9001 and ISO 27001 across all departments to provide maintenance services, enhance customer satisfaction, and protect and effectively utilize various information assets of our customers. We are committed to establishing a system for providing higher quality services and products, striving to improve customer satisfaction, and delivering services that ensure safety and security with thorough information security measures.

Inspection and Maintenance Service Technology for EOSL Parts We are facing many technical and engineering challenges to supply EOSL parts without relying on manufacturers. We are committed to building high quality through technology and inheritance, handling precision electronic components, and establishing systems and facilities to ensure stable quality while accumulating knowledge.

Quality Control of Individual Parts Memory, storage media, power units, and expansion cards incorporated into maintenance-targeted equipment are managed for part numbers, versions, and quality on an individual part basis. The quality of storage media that retains data is particularly important. Our company has customized and implemented inspection equipment for storage media to enhance the initial recovery rate from failures for long-term use.

The equipment information and maintenance registration information provided by customers for quotation requests are treated as confidential information. We check inventory not only by model and product name but also at the part number and model number level to allocate maintenance parts. The accuracy of the registration information supports a high initial recovery rate during failures.

Even during the pandemic, we handle meetings remotely. We will also adjust to customize maintenance schemes and response flows for each system in relation to the maintenance of critical systems. We carefully address details such as parts deployment methods, delivery units, access to and from data centers, and reporting methods for maintenance work, building individual flows. This enhances the quality of our services and reduces the operational burden on the systems.

Establish a rich inventory of stock and generously equip spare parts in preparation for emergencies. A substantial stockpile enhances trust in maintenance services.

In preparation for future maintenance targets and consumption due to failures, we are working daily to receive the necessary quantities and to carry out maintenance and inspections.

Equipped with a lab environment, we strive to improve the initial recovery rate from failures and expand the maintenance target equipment by conducting pre-rehearsals as verification tests for replacement procedures and hardware combinations in critical system maintenance.
