6. Installation and Maintenance

• Installation Method: Usually adopts rail mounting (such as 6U or 8U chassis) and connects to the main control unit through the backplane. Strict anti-static measures are required during the installation process.
• Maintenance Strategy: Supports Hot-Swap, which means replacing faulty boards without turning off the system power, minimizing downtime losses to the greatest extent.
• Spare Parts Management: It is recommended to establish an authentic spare parts library to ensure rapid response and recovery when the system fails.
