Troubleshooting

This section addresses common issues you might encounter with your DGS-1210-28 switch.

No Power Indicator Light

• Verify that the power cord is securely connected to both the switch and a working power outlet.
• Check the power outlet by plugging in another device.
• Ensure the power switch (if present) is in the 'On' position.

No Network Connectivity on a Port

• Check the Ethernet cable connection at both ends (switch port and connected device). Try a different cable.
• Verify that the Link/Act LED for the specific port on the switch is illuminated. If not, there might be an issue with the cable or the connected device.
• Ensure the connected device is powered on and its network adapter is functioning correctly.
• Use the switch's Cable Diagnostics feature via the Web UI to test the cable integrity.
• If using an SFP port, ensure the SFP transceiver is properly seated and compatible with the fiber optic cable and the connected device.

Cannot Access Web Management Interface

• Ensure your computer's IP address is in the same subnet as the switch's IP address.
• Verify that you are using the correct IP address for the switch. If unsure, you may need to reset the switch to factory defaults (refer to the QIG for instructions).
• Disable any firewall or antivirus software on your computer temporarily to rule out interference.
• Try accessing the interface from a different web browser.

Network Performance Issues

• Check for network loops using the switch's Spanning Tree Protocol (STP) or Loopback Detection features.
• Monitor port utilization via the Web UI to identify congested ports. Consider enabling Bandwidth Control or configuring QoS for critical applications.
• Ensure all connected devices are operating at their optimal speed (Gigabit Ethernet where supported).
