• Harsh Industrial Environments: Adaptable to a wide temperature range of -40°C to +85°C, meeting the long-term stable operation requirements of various complex and harsh industrial environments.

Installation and Maintenance

Installation Precautions

• Anti-static Protection: As an ESD-sensitive board, anti-static gloves must be worn during the entire installation process. Direct contact with the PCB conductive circuits and chip pins is strictly prohibited to avoid static breakdown damage.
• Standard Rack Installation: Install the board strictly in accordance with the 2U standard rack specifications to ensure firm physical connection and good contact of interface terminals.
• Environment Control: Installation and commissioning shall be carried out in an air-conditioned equipment room with good ventilation and heat dissipation. The on-site operating ambient temperature shall be controlled within 0°C to +45°C.

Maintenance Guidelines

• Standard Storage Conditions: When not in use, the board shall be stored in a dedicated anti-static box to avoid dust, moisture and static erosion, so as to protect its electrical performance.
• Regular Detection: Use professional system software maintenance tools to query device diagnosis information and alarm records regularly, and collect timestamp-based diagnosis alarm data for equipment status analysis and fault prediction.
• Fault Repair Process
  • Carry out rapid equipment testing and accurately locate fault causes;
  • Implement standardized maintenance operations in a constant-temperature and anti-static controlled environment;
  • Replace aging and damaged components, and complete professional reflow soldering processing;
  • Finish equipment cleaning and anti-rust maintenance to restore working conditions;
  • Conduct FVT (Functional Verification Test) based on OEM standards to confirm that the board performance meets operational requirements.
