8. Troubleshooting
This section provides solutions to common issues. For more complex problems, consult Cisco's official documentation or technical support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Switch does not power on. | No power, faulty power cord, or power supply issue. | Verify power cord connection. Check power outlet. Test with a different power cord if available. |
| No link light on a connected port. | Incorrect cable, faulty cable, device not powered on, or port disabled. | Ensure cable is correctly connected. Try a different cable. Verify the connected device is powered on. Check port status in CLI. |
| Cannot access switch via console. | Incorrect console cable, wrong terminal settings, or faulty console port. | Ensure correct console cable (RJ-45 to DB-9). Verify terminal emulation settings (9600, 8, N, 1). |
8.1 Factory Reset
Performing a factory reset will erase all configurations and restore the switch to its default settings. This procedure should only be performed if necessary and with caution. Consult Cisco documentation for the specific CLI commands to perform a factory reset for the Catalyst 9300 series.
