3. Installation und Einrichtung

3.1 Auspacken und Prüfen

Carefully unpack the switch and inspect it for any damage during shipping. Report any damage to your vendor immediately.

3.2 Standortvorbereitung

Before installation, ensure the installation site meets the environmental requirements. The switch dimensions are approximately 17.5 x 15.2 x 1.75 inches (44.45 x 38.61 x 4.45 cm) or 17.5"L x 17.5"W x 2.9"H (44.45 x 44.45 x 7.37 cm) depending on specific mounting. Allow sufficient space for cabling and ventilation.

3.3 Montage des Schalters

The switch can be mounted in a standard 19-inch equipment rack. Use the provided rack-mount brackets and screws to secure the switch. Ensure the switch is level and securely fastened.

3.4 Stromversorgung anschließen

1. Schließen Sie das Netzkabel an den Netzanschluss auf der Rückseite des Schalters an.
2. Stecken Sie das andere Ende des Netzkabels in eine geerdete Wechselstromsteckdose.
3. Prüfen Sie, ob die System-LED auf der Vorderseite leuchtet. Dies zeigt an, dass die Stromversorgung gewährleistet ist.

3.5 Netzwerkgeräte anschließen

Connect network devices (computers, IP phones, wireless access points) to the 48 10/100/1000Base-T Ethernet ports using standard Ethernet cables. For devices requiring power, connect them to the PoE+ enabled ports. Use SFP modules in the expansion slots for fiber optic or other uplink connections.

3.6 Zugriff auf die Erstkonfiguration

For initial configuration, connect a console cable from your management workstation to the console port on the switch. Use a terminal emulation program (e.g., PuTTY, Tera Term) with appropriate settings (typically 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control) to access the command-line interface (CLI).

4. Bedienung

4.1 Ein-/Ausschalten

Once connected to a power source, the switch will automatically power on. There is no physical power button. To power off, disconnect the power cord. For proper shutdown, it is recommended to save configurations before disconnecting power.

4.2 LED-Anzeigen

The front panel of the switch features various LEDs to indicate system status and port activity:

• System-LED: Indicates overall system health (e.g., green for normal operation, amber for issues).
• RPS LED: Indicates the status of the Redundant Power System (if installed).
• LED-Stapel: Indicates the status of the FlexStack connection.
• Port-Status-LEDs: Each Ethernet port has an LED to indicate link status (on/off) and activity (blinking). Green typically indicates a 1000 Mbps link, amber for 10/100 Mbps.
• PoE-LED: Indicates Power over Ethernet status for the respective port.

4.3 Power over Ethernet Plus (PoE+)

The switch supports PoE+ (802.3at) on all 48 Ethernet ports, providing up to 30W of power per port to compatible devices such as IP phones, wireless access points, and surveillance cameras. Ensure connected devices are PoE+ compliant for optimal performance.

4.4 Cisco FlexStack

The Cisco Catalyst 2960S-48LPS-L supports FlexStack technology, allowing multiple switches to be stacked together to operate as a single logical unit. This simplifies management and increases network scalability. Refer to the Cisco documentation for detailed FlexStack configuration and cabling instructions.

5. Wartung

5.1 Cleaning the Switch

Periodically clean the exterior of the switch with a soft, dry, lint-free cloth. Do not use liquid or aerosol cleaners, as they may contain flammable substances or cause electrical shock. Ensure ventilation openings are free from dust and debris.

5.2 Firmware-Updates

Regularly check the Cisco website for the latest firmware updates. Keeping the switch firmware up-to-date ensures optimal performance, security, and access to new features. Follow the instructions provided by Cisco for the update process.

5.3 Umweltüberwachung

Monitor the operating environment to ensure it remains within the specified temperature and humidity ranges. Excessive heat can reduce the lifespan of the device. The upper temperature rating is 40 degrees Celsius.

6. Fehlerbehebung

This section provides solutions to common issues you might encounter with your Cisco Catalyst switch.

6.1 Kein Strom

• Verify the power cord is securely connected to both the switch and a working power outlet.
• Prüfen Sie die Steckdose mit einem anderen Gerät, um sicherzustellen, dass sie funktionsfähig ist.
• Überprüfen Sie das Netzkabel auf eventuelle Beschädigungen.
• Ensure the system LED on the front panel is illuminated.

6.2 Keine Verbindung an einem Port

• Stellen Sie sicher, dass das Ethernet-Kabel sowohl mit dem Switch-Port als auch mit dem Netzwerkgerät fest verbunden ist.
• Check the cable for damage and try a different cable.
• Verify the network device is powered on and functioning correctly.
