3. Producte acabatview

3.1 Tauler frontal

This image displays the front panel of the Cisco SF352-08P Managed Switch. From left to right, it features a USB port, System and Reset buttons, eight 10/100 PoE Ethernet ports with corresponding Link/Act and PoE status LEDs, and two Gigabit Ethernet (GbE) combo SFP ports (G1 and G2) with their own Link/Act LEDs. The model number 'SF352-08P 8-Port 10/100 PoE Managed Switch' is printed below the ports.

The front panel of the SF352-08P switch provides access to network ports, status indicators, and management interfaces.

• Port USB: Used for firmware upgrades or configuration backup/restore.
• LED del sistema: Indicates the overall status of the switch.
• Botó de restabliment: Used to reset the switch or restore factory default settings.
• 8 x 10/100 PoE Ports: RJ-45 ports for connecting network devices, supporting Power over Ethernet (PoE). Each port has Link/Act and PoE status LEDs.
• 2 x Gigabit Combo SFP Ports (G1, G2): These ports can function as either RJ-45 Gigabit Ethernet ports or SFP (Small Form-Factor Pluggable) fiber optic ports. Each has a Link/Act LED.

4. Configuració

4.1 Instal·lació física

The SF352-08P switch can be installed on a desktop or mounted in a standard 19-inch equipment rack.

• Instal·lació d'escriptori: Attach the included rubber feet to the bottom of the switch to prevent scratching surfaces and ensure stability. Place the switch on a flat, stable surface with adequate ventilation.
• Rack-Mount Installation: Use the provided rack-mount kit to secure the switch in a standard 19-inch equipment rack. Ensure proper airflow around the device.

4.2 Connexió d'alimentació

Connect the provided power cord to the power input on the rear panel of the switch and then to a grounded electrical outlet. The System LED on the front panel will illuminate when power is supplied.

4.3 Connexió de xarxa

Connect your network devices (computers, servers, IP phones, access points) to the 10/100 PoE ports using standard Ethernet cables. For higher bandwidth connections or fiber optic links, use the Gigabit Combo SFP ports.

4.4 Accés a la configuració inicial

El commutador es pot configurar mitjançant un web-based Graphical User Interface (GUI) or a Command Line Interface (CLI).

• Web GUI: Connect a computer to any of the switch's Ethernet ports. The switch will typically obtain an IP address via DHCP. If no DHCP server is present, it will default to 192.168.1.254. Open a web browser and enter the switch's IP address. Log in using the default credentials (refer to the Quick Start Guide for initial username/password).
• CLI: Use the provided DB-9 to RJ45 serial cable to connect your computer's serial port to the console port on the switch. Use a terminal emulation program (e.g., PuTTY, Tera Term) with appropriate settings (e.g., 115200 baud, 8 data bits, no parity, 1 stop bit, no flow control).

5. Funcionament de l'interruptor

5.1 Configuració bàsica de xarxa

The SF352-08P supports various Layer 2 and Layer 3 features for network management and optimization.

• VLAN: Create Virtual Local Area Networks to segment network traffic and improve security and performance.
• Qualitat de servei (QoS): Prioritize critical network traffic (e.g., voice, video) to ensure consistent performance.
• Encaminament estàtic: Configure static routes for inter-VLAN routing or to direct traffic to specific network segments.
• Auto Smartports: Automatically apply optimal configurations to ports based on the detected device type.

5.2 Power over Ethernet (PoE)

The 10/100 ports on the SF352-08P provide Power over Ethernet, allowing compatible devices (e.g., IP phones, wireless access points, IP cameras) to receive power and data over a single Ethernet cable. The switch has a total PoE power budget of 62W.

6. Manteniment

6.1 actualitzacions de microprogramari

Consulteu periòdicament el suport tècnic de Cisco website for the latest firmware versions. Updating the firmware can provide new features, performance improvements, and security enhancements. Follow the instructions provided with the firmware download for the update process.

6.2 Restabliment del dispositiu

The reset button on the front panel can be used for two functions:

• Restabliment suau: A brief press (less than 5 seconds) will reboot the switch without losing configuration.
• Restabliment de fàbrica: Press and hold the reset button for more than 10 seconds to restore the switch to its factory default settings. All configurations will be lost.

7. Solució De Problemes

This section provides solutions to common issues you might encounter with the SF352-08P switch.

• Sense energia: Ensure the power cord is securely connected to the switch and a working electrical outlet. Check the System LED.
• Sense enllaç al port: Verify the Ethernet cable connection at both ends. Check the Link/Act LED for the port. Ensure the connected device is powered on and functioning correctly.
• El dispositiu PoE no s'encén: Check the PoE LED for the port. Ensure the connected device is PoE-compatible and that the switch's PoE budget is not exceeded.
• No es pot accedir Web GUI: Verify your computer's IP address is in the same subnet as the switch. Try pinging the switch's IP address. Clear your browser's cache or try a different browser.
• Rendiment de xarxa lent: Check for network loops (ensure Spanning Tree Protocol is enabled if needed). Verify cable quality and length. Check for excessive broadcast traffic.

If issues persist, consult the comprehensive Cisco documentation available online or contact Cisco technical support.
