2. Einrichtung und Installation

2.1 Auspacken und Prüfen

Carefully unpack the switch and verify that all components are present and undamaged. The package should contain:

• Cisco Catalyst 2960S-48TD-L Ethernet Switch
• Netzkabel
• Rack-mount kit (if included)
• Dokumentation (Schnellstartanleitung, Sicherheitshinweise)

If any items are missing or damaged, contact your Cisco representative immediately.

2.2 Rackmontage

The switch can be mounted in a standard 19-inch equipment rack. Follow these steps:

1. Attach the rack-mount brackets to the sides of the switch using the provided screws.
2. Align the switch with the rack posts and secure it using the rack screws.
3. Sorgen Sie für ausreichende Luftzirkulation um den Schalter herum, um eine ordnungsgemäße Kühlung zu gewährleisten.

2.3 Stromversorgung anschließen

Connect the supplied AC power cord to the power connector on the rear panel of the switch and then to a grounded AC power outlet. The switch will automatically power on once connected.

2.4 Netzwerkverbindungen

Connect Ethernet cables from your network devices (computers, servers, other switches) to the RJ-45 ports on the front panel. For high-speed uplinks, use appropriate SFP+ transceivers and fiber optic cables in the dedicated SFP+ slots.

3. Bedienungsanleitung

3.1 Erstes Einschalten

Upon connecting power, the switch will initiate its boot sequence. Observe the system LED on the front panel. It will cycle through various states (amber, green) and eventually turn solid green, indicating successful boot-up and readiness for operation.

3.2 Zugriff auf den Switch

You can access and configure the switch using several methods:

• Konsolenport: Connect a console cable (RJ-45 to DB-9) from your management workstation to the console port on the rear panel. 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.
• Telnet/SSH: Once the switch has an IP address configured, you can access it remotely via Telnet (less secure) or SSH (recommended for security) using its IP address.
• Web Interface (HTTP/HTTPS): If enabled and configured, you can access the switch's web-basierte Verwaltungsschnittstelle durch Eingabe ihrer IP-Adresse in eine web Browser.

3.3 Grundkonfiguration

Refer to the Cisco IOS Software Configuration Guide for detailed configuration instructions. Common initial configurations include:

• Setting the hostname
• Configuring IP addresses for management interfaces (VLAN 1 by default)
• Setting up user accounts and passwords
• Enabling SSH for secure remote access
• Configuring VLANs and port assignments

4. Wartung

4.1 Reinigung

Periodically clean the exterior of the switch with a soft, dry cloth. Ensure that the ventilation openings are free from dust and debris to maintain proper airflow and prevent overheating. Do not use liquid or aerosol cleaners directly on the switch.

4.2 Firmware-Updates

Regularly check the Cisco website for the latest firmware (IOS) updates for your switch model. Keeping the firmware up-to-date ensures optimal performance, security, and access to new features. Follow Cisco's recommended procedures for firmware upgrades to avoid service interruptions.

5. Fehlerbehebung

5.1 Stromversorgungsprobleme

• Kein Strom: Vergewissern Sie sich, dass das Netzkabel fest mit dem Schalter und der Steckdose verbunden ist. Testen Sie die Steckdose mit einem anderen Gerät.
• System-LED aus: If the system LED is off after connecting power, the switch may not be receiving power or could be faulty.

5.2 Probleme mit der Netzwerkverbindung

• Port LED Off: Ensure the Ethernet cable is properly connected at both ends. Check the connected device for power and proper operation.
• Kein Netzwerkzugriff: Verify IP configuration on the switch and connected devices. Check VLAN assignments and ensure routing is correctly configured if necessary.

5.3 Leistungsprobleme

• Langsames Netzwerk: Check for high CPU utilization on the switch. Inspect port statistics for errors, collisions, or excessive broadcasts. Consider upgrading to higher-speed uplinks if bandwidth is a bottleneck.
• Intermittierende Konnektivität: Inspect cables for damage. Check for duplex mismatches between the switch port and the connected device.
