Print Server Restarts or Shuts Down When Connecting a USB Cable to a Printer
Cause Analysis:
- Poor Quality or Damaged USB Cable: The USB cable might be faulty or of low quality, causing connectivity issues.
- External Electromagnetic Interference (EMI): External electromagnetic fields can disrupt the electrical circuits within the USB connection, leading to instability and potential shutdowns or restarts.
- USB Port Issues: Damage to the USB port on the print server due to physical stress or faulty cables can cause connectivity issues, leading to instability when devices are connected.
Resolution Steps:
- Use High-Quality, Anti-Interference USB Cables:
- Employ USB cables equipped with ferrite beads to significantly reduce electromagnetic interference. Ensure the cables are of high quality and in good condition to enhance system stability and prevent data transmission issues.
- Check USB Ports:
- Connect a USB flash drive or another device that does not require separate power to the print server to assess the functionality of the USB ports. If the indicator does not light up, suggesting a hardware issue, contact your dealer for repair services.
