5. Einrichtung

5.1 Rackmontage

1. Befestigen Sie die mitgelieferten Rack-Montagehalterungen mithilfe der beiliegenden Schrauben an den Seiten des Switches.
2. Secure the switch into a standard 19-inch equipment rack using appropriate rack screws. Ensure adequate clearance for airflow.

5.2 Stromanschluss

1. Connect the power cord to the AC power receptacle on the rear of the switch.
2. Stecken Sie das andere Ende des Netzkabels in eine geerdete Steckdose.
3. Ensure the power supply is properly seated and secured.

5.3 Netzwerkverbindungen

• Connect Ethernet cables from your network devices (computers, access points, IP phones) to the 48 Gigabit Ethernet ports on the front panel.
• For uplink connectivity, install the appropriate uplink module (if not pre-installed) and connect fiber or copper cables to your core network or other switches.
• For stacking, connect StackWise-480 cables between the stack ports of multiple Catalyst 9300 switches.

5.4 Erstkonfiguration

1. Connect a computer to the console port using the provided console cable.
2. Use a terminal emulation program (e.g., PuTTY, Tera Term) with settings: 9600 baud, 8 data bits, no parity, 1 stop bit, no flow control.
3. Power on the switch. The boot process will display messages on the console.
4. Follow the on-screen prompts to perform initial setup, including setting the hostname, IP address, and administrative passwords.

6. Bedienung des Schalters

6.1 Ein-/Ausschalten

To power on the switch, ensure the power cord is securely connected to a live outlet. The switch will automatically begin its boot sequence. To power off, disconnect the power cord. For graceful shutdown, use the appropriate command-line interface (CLI) commands.

6.2 LED-Anzeigen

Monitor the LED indicators on the front panel to understand the switch's operational status:

• System-LED: Zeigt den allgemeinen Systemzustand an (z. B. grün für normal, gelb für Warnung, rot für kritisch).
• PoE-LED: Shows the status of Power over Ethernet (e.g., green for active PoE, amber for fault).
• Port-Status-LEDs: Indicate link status and activity for each network port (e.g., green for link, blinking for activity).

6.3 Geräte anschließen

Connect network devices to the Gigabit Ethernet ports. For devices requiring power, ensure they are PoE-compatible and the switch's PoE budget is sufficient. The switch automatically detects and provides power to PoE-enabled devices.

6.4 Erweiterte Funktionen

The Cisco Catalyst 9300 supports advanced features such as:

• StackWise Virtual: For creating a single logical switch from multiple physical switches.
• Cisco IOS XE: A modern, programmable operating system for advanced network management and automation.
• Sicherheitsfunktionen: Integrated security for threat detection and mitigation.

7. Wartung
