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 and conduct quality inspections. We will stock a sufficient quantity and quality of maintenance replacement parts.

ISO 9001 Certification 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 In order to supply EOSL parts without relying on manufacturers, we are facing many technical and engineering challenges. We are committed to building high quality through technology and inheritance, as well as handling precision electronic components with facilities and systems, striving to supply with stable quality and accumulate knowledge.

Quality control of individual parts Memory, storage media, power units, and expansion cards incorporated into the equipment subject to maintenance are managed for part number information, version, 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 inquire about inventory not only by model and product name but also at the part number and type 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 also adjust to customize maintenance schemes and response flows for critical systems, which differ by system. We carefully address details such as parts deployment methods, unit delivery, 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 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 strive to receive the necessary quantities daily and focus on maintenance and inspection.

We have also equipped inspection facilities for network devices, and we will promptly conduct inspections for main unit replacements, as well as assess port activity and deterioration.
