5. Fejlfinding

This section provides solutions to common issues you might encounter with your EX3200-24T switch.

5.1 Ingen strøm

• Symptom: No LEDs are illuminated, and the switch does not power on.
• Handling:
  • Kontroller, at netledningen er korrekt tilsluttet til både afbryderen og stikkontakten.
  • Sørg for, at tænd/sluk-knappen på bagpanelet er i ON-positionen.
  • Check the electrical outlet with another device to confirm it is functional.
  • If using a power strip or UPS, ensure it is powered on and functioning correctly.

5.2 Ingen netværksforbindelse

• Symptom: Devices connected to the switch cannot access the network.
• Handling:
  • Check the port LEDs on the switch for the connected device. A solid green LED indicates a link. If no link, try a different port or cable.
  • Verify the network cable is securely connected at both ends (switch and device).
  • Sørg for, at den tilsluttede enheds netværkskort er aktiveret og konfigureret korrekt.
  • If multiple devices are affected, check the uplink connection from the EX3200-24T to your core network.
  • Consult the switch's configuration for VLANs, IP addressing, and other network settings.

5.3 System Alarm LED (ALM) is Amber/Red

• Symptom: The ALM LED is illuminated amber or red.
• Handling:
  • Log in to the switch via the console or network management interface.
  • Check system logs and alarm messages for details on the specific issue.
  • Common causes include power supply issues, fan failures, or high temperature.
