Hardware Verification and Testing

Hardware Verification

Kognitive Networks works directly with OEMs (Original Equipment Manufacturers) to procure, customize, and configure devices to a custom specification. Kognitive Networks validates and periodically reassess each hardware partner on the following criteria:

1. Quality and Reliability: Evaluate the supplier's quality management system, track record, product testing, and documentation to ensure high standards.

2. Financial Stability: Assess the supplier’s financial health, business history, and credit rating to ensure long-term sustainability.

3. Supply Chain Capabilities: Ensure the supplier has the production capacity, lead times, and flexibility to meet demand and adapt to changes.

4. Technical Expertise and Innovation: Evaluate the supplier’s R&D capabilities, technical support, and after-sales service for continuous innovation and support.

5. Sustainability and Compliance: Verify the supplier’s compliance with environmental standards, industry regulations, and corporate social responsibility practices.

Hardware Testing

All hardware products are verified by the manufacturer, but also undergo rigorous in-house testing to ensure they meet Kognitive Networks' functional and performance standards. Each piece of hardware is serialized after passing these tests, ensuring traceability. The software used for testing hardware is managed through version control to maintain consistency and integrity in testing procedures.

Acceptance Test Procedure (ATP) for Hardware

Kognitive Networks implements a detailed Hardware Acceptance Test Procedure (ATP) to ensure that each hardware Device Under Test (DUT) meets manufacturing standards, minimum performance metrics, and functional demands. The ATP for hardware involves several key steps:

Test Environment Setup

• Hardware and Tools: Preparation of the hardware testing environment with necessary tools, fixtures, and equipment calibrated for accuracy.

• Configuration: Configuration of the hardware interfaces as per the operational specifications to mimic real-world usage conditions.

Functional Testing

• Operational Checks: Verification that all functional aspects of the hardware operate as intended. This includes power-up procedures, device initialization, and interface testing.

• Feature Testing: Detailed testing of each specific feature as outlined in the product specifications to ensure full functionality.

Configuration

• Validation: Checking proper software load, configuration, and base functionality.

• Serialization: Physical and digital checks to validate consistent serialization on a single DUT.

Performance Testing

• Stress Testing: Subjecting the hardware to high-stress conditions to ensure it maintains functionality under extreme operational conditions.

Reporting and Feedback

• Test Results Compilation: Documenting the outcomes of all tests, including pass/fail status for each test case and any deviations from expected results.

• Issue Logging and Resolution: Recording any non-conformances or defects identified during testing and detailing corrective actions taken.

Documentation

• ATP Documentation: All procedures and software are documented in a version control system.

• Test Records: All test results and approval records are stored in a test database. These records are available for diagnostics and analysis in the case of anomalies in the field.

• Test Report: Individual device Test Reports are generated and printed at the conclusion of the functional test, to be included with the hardware shipment.

The ATP ensures that every piece of hardware shipped by Kognitive Networks meets stringent quality standards, thus safeguarding both functionality and customer satisfaction. This systematic approach to testing and validation is crucial in maintaining the reliability and market reputation of Kognitive Networks' hardware products.
