4. Einrichtung

4.1 Auspacken und Prüfen

Carefully unpack the switch and verify that all components are present and undamaged. If any items are missing or damaged, contact your vendor.

4.2 Standortvorbereitung

Stellen Sie sicher, dass der Installationsort folgende Anforderungen erfüllt:

• Adequate ventilation to prevent overheating.
• Stable surface for desktop placement or a standard 19-inch equipment rack.
• Proximity to a grounded power outlet.
• Operating temperature and humidity within specified ranges (refer to specifications).

4.3 Montage des Schalters

Der Switch kann auf einem Schreibtisch platziert oder in einem Standard-19-Zoll-Geräteschrank montiert werden.

• Desktop-Platzierung: Place the switch on a flat, stable surface, ensuring sufficient space around the device for airflow.
• Rackmontage: Attach the provided rack-mount brackets to the sides of the switch using the supplied screws. Secure the switch into the equipment rack using appropriate rack screws.

4.4 Stromversorgung anschließen

1. Connect one end of the AC power cord to the power connector on the rear panel of the switch.
2. Schließen Sie das andere Ende des Netzkabels an eine geerdete Steckdose an.
3. The switch will power on automatically. Observe the System LED on the front panel; it should turn green after a brief startup sequence.

4.5 Netzwerkgeräte anschließen

Use standard Ethernet cables (Category 5 or higher) to connect your network devices (computers, servers, routers, etc.) to the RJ45 ports on the front panel of the switch.

• Insert one end of the Ethernet cable into a port on your network device.
• Insert the other end of the Ethernet cable into any of the 24 RJ45 ports on the switch.
• Verify the Port Status LED for the connected port. A solid green LED indicates a successful link. A blinking green LED indicates network activity.

4.6 Zugriff auf die Erstkonfiguration

To perform initial configuration or advanced management, connect to the switch's console port:

1. Connect an RJ-45 to DB-9 console cable (often referred to as a rollover cable) to the console port on the rear of the switch.
2. Connect the DB-9 end of the cable to the serial port of a computer.
3. Open a terminal emulation program (e.g., PuTTY, Tera Term) on the computer and configure it with the following settings: 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control.
4. Press Enter to access the switch's Command Line Interface (CLI).

5. Bedienung

5.1 Ein- und Ausschalten

The switch powers on automatically when connected to a power source. To power off, disconnect the power cord from the electrical outlet.

5.2 LED-Anzeigen verstehen

• System-LED:
  • Solid Green: System is operating normally.
  • Amber: System is performing POST (Power-On Self-Test) or has encountered an issue.
• Port-Status-LEDs:
  • Solid Green: Link established.
  • Blinking Green: Activity on the port.
  • Off: No link or port disabled.

5.3 Grundlegende Netzwerkverbindungen

Once powered on and devices are connected, the switch will automatically forward Ethernet frames between connected devices. For advanced network configurations, such as VLANs or security settings, use the Command Line Interface (CLI) via the console port or a configured in-band management interface.

6. Wartung

6.1 Reinigung

To maintain optimal performance, periodically clean the exterior of the switch with a soft, dry cloth. Ensure the power is disconnected before cleaning. Do not use liquid or aerosol cleaners directly on the device.

6.2 Umweltaspekte

Ensure the switch operates within its specified temperature and humidity ranges. Avoid blocking ventilation openings to prevent heat buildup.

6.3 Firmware-Updates

Periodically check the Cisco website for available firmware updates. Updating the firmware can provide new features, performance improvements, and security enhancements. Follow Cisco's official documentation for firmware upgrade procedures.

7. Fehlerbehebung

7.1 Kein Strom

• Vergewissern Sie sich, dass das Netzkabel fest mit dem Schalter und einer funktionierenden Steckdose verbunden ist.
• Prüfen Sie die Steckdose mit einem anderen Gerät, um sicherzustellen, dass sie funktionsfähig ist.
• Ensure the System LED is illuminated. If not, contact support.

7.2 Keine Verbindung an einem Port

• Stellen Sie sicher, dass das Ethernet-Kabel an beiden Enden fest angeschlossen ist.
• Versuchen Sie es mit einem anderen Ethernet-Kabel.
• Schließen Sie das Gerät an einen anderen Port des Switches an.
• Vergewissern Sie sich, dass das angeschlossene Gerät eingeschaltet ist und ordnungsgemäß funktioniert.
• Check the Port Status LED. If it remains off, there might be an issue with the cable, the connected device, or the switch port.

7.3 Probleme mit der Netzwerkverbindung

• Confirm that all devices have valid IP addresses and subnet masks.
• Check for IP address conflicts.
• If using advanced configurations (VLANs, routing), verify the configuration via the CLI.
• Perform basic network tests like pinging other devices on the network.
