Resolució de problemes
This section provides basic troubleshooting steps for common issues. For more complex problems, refer to the official user manual or contact Cisco support.
Sense poder
- Verify the power cord is securely connected to the switch and the electrical outlet.
- Comproveu si la presa de corrent funciona connectant-hi un altre dispositiu.
- Ensure the power switch (if present) is in the ON position.
Sense connectivitat de xarxa
- Check the Ethernet cables connecting devices to the switch ports. Ensure they are properly seated and not damaged.
- Observe the link/activity LEDs on the switch ports. A solid green or amber light typically indicates a valid link, while blinking indicates activity. No light suggests a cable or device issue.
- Verify the network settings (IP address, subnet mask, gateway) on the connected devices.
- If using SFP+ ports, ensure the correct transceivers are used and fiber optic cables are clean and properly connected.
- Accés a l'interruptor web UI to check port status and configuration.
Slow Network Performance
- Check for excessive network traffic or broadcast storms using the switch's monitoring tools.
- Ensure all devices are operating at their optimal speed (e.g., Gigabit Ethernet for Gigabit ports).
- Verify duplex settings are consistent between the switch port and the connected device.
- Consider implementing QoS (Quality of Service) to prioritize critical applications.
