Cisco Catalyst 2975 48-Port LAN Base Switch

Einführung

This manual provides essential instructions for the installation, operation, maintenance, and troubleshooting of the Cisco Catalyst 2975 48-Port LAN Base Switch (Model: WS-C2975GS-48PS-L). This device is designed to provide enhanced LAN services for commercial branch office networks, offering Gigabit Ethernet and Power over Ethernet (PoE) connectivity.

Produkt überview

The Cisco Catalyst 2975 LAN Base Switch is a fixed-configuration, stackable intelligent Ethernet switch. It features 48 ports with Gigabit Ethernet and Power over Ethernet (PoE) capabilities, enabling efficient network connectivity and power delivery to compatible devices. Key features include high-speed stacking for up to nine switches and unified stack management for simplified network administration.

This image displays the front panel of the Cisco Catalyst 2975 switch. It features 48 RJ-45 Ethernet ports, arranged in groups, along with status indicator LEDs above each port group. On the far right, there are four additional uplink ports, likely SFP or Gigabit Ethernet, and more status indicators. The overall design is a standard rack-mountable network switch.

Aufstellen

1. Auspacken und Inspektion: Carefully remove the switch from its packaging. Inspect the device for any signs of physical damage. Report any damage to your supplier immediately. Ensure all components listed in the packing list are present.
2. Montage: Der Switch kann in einem Standard-19-Zoll-Geräteschrank installiert oder auf einem Schreibtisch platziert werden.
   • Rackmontage: Attach the provided rack-mount brackets to the sides of the switch using the supplied screws. Secure the switch into the rack using appropriate rack screws.
   • Desktop-Platzierung: Ensure the surface is flat, stable, and allows for adequate ventilation around the switch. Attach the rubber feet to the bottom of the switch if not already present.
3. Strom anschließen: Connect the power cord to the AC power connector on the rear of the switch and then to a grounded AC power outlet. The switch will power on automatically.
4. Connecting Network Cables: Connect Ethernet cables from your network devices (computers, servers, access points) to the RJ-45 ports on the front panel. For devices requiring Power over Ethernet (PoE), ensure they are connected to PoE-enabled ports. Use appropriate Gigabit Ethernet cables (Category 5e or higher) for optimal performance.
5. Erstkonfigurationszugriff: For initial configuration, connect a console cable (RJ-45 to DB-9) from your management workstation to the console port on the switch. 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.

Betrieb

• LED-Anzeigen: Observe the front panel LEDs to monitor switch status, port activity, and PoE status. Refer to the detailed LED status guide in the full product documentation for specific interpretations.
• Stapeln: The Catalyst 2975 supports high-speed stacking. Connect multiple switches using dedicated stacking cables to form a single logical unit, simplifying management and increasing port density. Follow the stacking guide for proper cable connections and configuration.
• Power-over-Ethernet (PoE): PoE ports automatically detect and provide power to compatible PoE-enabled devices (e.g., IP phones, wireless access points, IP cameras) connected via Ethernet cables. Ensure the total power budget is not exceeded.
• Management: The switch can be managed via a Command Line Interface (CLI) accessible through the console port or Telnet/SSH, or through a web-based graphical user interface (GUI) if enabled. Refer to the Cisco IOS Software Configuration Guide for detailed management instructions.

Wartung

• Reinigung: Keep the switch clean and free of dust. Use a soft, dry cloth to wipe the exterior. Do not use liquid or aerosol cleaners directly on the switch. Ensure ventilation openings are clear of obstructions.
• Firmware-Updates: Überprüfen Sie regelmäßig den Cisco-Support. website for available firmware updates. Applying updates can improve performance, add features, and address security vulnerabilities. Follow the provided instructions carefully when performing firmware upgrades.
• Umweltaspekte: Operate the switch within its specified temperature and humidity ranges. Ensure proper airflow to prevent overheating. Avoid exposing the switch to direct sunlight, excessive moisture, or extreme temperatures.

Fehlerbehebung

• Kein Strom: If the switch does not power on, verify the power cord is securely connected to both the switch and a working power outlet. Check the power source and any circuit breakers.
• Keine Verbindung/Konnektivität: If a device is not connecting, check the Ethernet cable for damage and ensure it is properly seated in both the switch port and the device. Verify the link status LED on the switch port. Try a different port or cable.
• PoE Issues: If a PoE device is not receiving power, ensure it is connected to a PoE-enabled port. Check the PoE status LED for the port. Verify the switch's total PoE power budget is not exceeded.
• Langsame Netzwerkleistung: Check for excessive network traffic, duplex mismatches, or faulty cables. Ensure all devices are operating at their intended speeds (e.g., Gigabit Ethernet).
• Werkseinstellungen zurückgesetzt: In case of severe configuration issues, a factory reset may be performed. Refer to the Cisco documentation for the specific procedure, as this will erase all configurations.
