7. Troubleshooting
This section provides solutions to common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Switch does not power on. | No power, faulty power cord, or power supply issue. | Verify power cord connection to switch and outlet. Check outlet functionality. Ensure voltage matches specifications. |
| Port LED is off or amber. | No link, incorrect cable, or faulty transceiver. | Check cable connection at both ends. Ensure correct cable type (fiber/DAC) and transceiver. Verify connected device is powered on and configured correctly. |
| Cannot access management interface. | Incorrect IP configuration, network issue, or firewall. | Verify switch IP address and subnet mask. Check network connectivity to the management port. Temporarily disable client firewall for testing. Try console access. |
| Poor network performance. | Congestion, misconfiguration, or faulty hardware. | Check port statistics for errors or discards. Verify duplex and speed settings. Ensure proper network design and avoid oversubscription. |
