Quality and quantity of replacement parts We have a procurement and production system that supports the EOSL maintenance business, maintaining the capability for procurement, stockpiling, and quality inspection of EOSL parts. We will stock a sufficient quantity and quality of maintenance replacement parts.

ISO 9001 Certification ISO 27001 Certification We have implemented ISO 9001 and ISO 27001 management systems and obtained certification across all departments to provide maintenance services, enhance customer satisfaction, and protect and effectively utilize various information assets of our customers. We strive to establish a system for providing higher quality services and products, improve customer satisfaction, and deliver 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 efforts that build up knowledge and provide stable quality, including technologies and inheritance for creating high quality, as well as facilities and systems for handling precision electronic components.

Quality control of individual parts Memory, storage media, power units, and expansion cards incorporated into maintenance-targeted equipment 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 check 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 will also adjust to customize maintenance schemes and response flows for each system in relation to the maintenance of critical systems. We meticulously address the deployment methods of parts, the units for bringing them in, access to and from the data center, and the 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 provide spare parts in preparation for any disruptions. 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 status and deterioration.
