Diagnosing random shutdowns in Poynt Terminals. Common power supply issues, cable faults, and ESD protection. Safe handling and maintenance tips.
The rating is typically printed on the power adapter label. Ensure it matches the terminal's requirements.
Use a receptacle tester to verify proper grounding of the power outlet.
Extreme environmental conditions can damage the power supply components.
Poynt Terminals operate on a specific voltage supplied via an external power adapter. Voltage fluctuations or current drops below the operational threshold can trigger a system shutdown. Electrostatic discharge (ESD), especially in dry environments, can interfere with the power management integrated circuits (PMIC). Signal attenuation within the power cable or connector corrosion increases resistance, leading to insufficient power delivery.
Poynt Terminal exhibits unexpected and intermittent power loss, resulting in complete shutdown. Shutdowns occur without warning and are not correlated to specific transactions or user actions.
Safe Handling: Disconnect the power adapter from the power outlet before inspecting cables or connectors. Avoid contact with liquids. Do not attempt to open the terminal casing as it contains tamper-evident mechanisms. Potential tripping hazard from loose cables. Static discharge can damage the terminal; ground yourself before touching connectors.
Regularly inspect power cables for damage.,Ensure adequate ventilation around the terminal.,Clean the terminal and power adapter connectors regularly with a dry, static-free brush.,Implement ESD control measures, especially during dry seasons (e.g., anti-static mats).,Avoid placing the terminal near sources of electromagnetic interference.
Use a power conditioner or surge protector to stabilize the power supply and protect against voltage spikes. Check the polarity of the power adapter's connector to ensure it matches the terminal's requirements. Some models may exhibit a brief delay after power-on; allow sufficient time for the terminal to initialize before assuming a failure.
