3. Configuració

3.1 Instal·lació física

The DN-95351 switch offers flexible installation options:

• Instal·lació d'escriptori: Attach the provided rubber feet to the bottom of the switch to prevent slipping and ensure proper ventilation. Place the switch on a stable, flat surface.
• 19-inch Rack Installation: Secure the included rack mount ears to the sides of the switch using the provided screws. Then, mount the switch into a standard 19-inch server rack. Ensure adequate space for airflow around the device.

3.2 Connexió d'alimentació

Connect the provided power cable to the AC power inlet on the rear panel of the switch and then to a standard electrical outlet. Ensure the power switch is in the 'Off' position before connecting, then switch it 'On' after all network connections are made.

3.3 Connexions de xarxa

• Ports RJ45 (1-16): Connect your network devices (computers, servers, IP cameras, access points, IP phones) to these 10/100/1000Base-TX Gigabit Ethernet ports using standard Ethernet cables. These ports support Power over Ethernet (PoE/PoE+) for compatible devices.
• SFP Uplink Ports (17-18): Use these 1 Gigabit SFP ports for fiber optic connections to other network devices, such as core switches or servers, for longer distances or higher bandwidth requirements. Insert compatible SFP modules (not included) into these slots.
• Port de la consola RJ45: This port is used for local management and configuration via a serial connection (e.g., using a console cable and terminal emulation software).

4. Funcionament

4.1 Power Over Ethernet (PoE) Functionality

The DN-95351 automatically detects and supplies power to devices that comply with IEEE802.3af/at standards. Each PoE+ port can deliver up to 30 watts, with a total power budget of 380 watts for all 16 ports. This simplifies deployment of PoE-enabled devices by eliminating the need for separate power adapters.

4.2 L2+ Management Features

This switch offers advanced Layer 2+ management capabilities for network optimization and security:

• VLAN (Xarxa d'Àrea Local Virtual): Segmenta la teva xarxa per millorar la seguretat i el rendiment.
• Mirall de ports: Supervisar el trànsit de xarxa enviant una còpia dels paquets d'un port a un altre.
• Port Aggregation (Link Aggregation): Combineu diversos enllaços físics en un únic enllaç lògic per augmentar l'amplada de banda i la redundància.
• SNMP (Protocol simple de gestió de xarxa): Remotely monitor and manage network devices.
• QoS (Qualitat de servei): Prioritzeu el trànsit de xarxa per garantir que les aplicacions crítiques rebin prou ample de banda.
• STP/RSTP/MSTP (Spanning Tree Protocols): Eviteu els bucles de xarxa i proporcioneu redundància de ruta.
• IEEE802.1X with ACL & Radius Authentication: Enhance network security by authenticating users and devices.

Detailed configuration instructions for these features can be found in the full data sheet or through the switch's web-based management interface or CLI.

5. Manteniment

To ensure optimal performance and longevity of your DIGITUS DN-95351 switch, follow these maintenance guidelines:

• Mantenir net: Netegeu regularment l'exterior de l'interruptor amb un drap suau i sec. Assegureu-vos que les obertures de ventilació estiguin lliures de pols i obstruccions.
• Condicions ambientals: Feu funcionar l'interruptor dins dels rangs de temperatura i humitat especificats. Eviteu exposar-lo a la llum solar directa, a la calor excessiva o a la humitat.
• Actualitzacions de firmware: Reviseu periòdicament el DIGITUS website for firmware updates. Keeping the firmware current can improve performance, add new features, and address security vulnerabilities.
• Gestió de cables: Assegureu-vos que tots els cables de xarxa estiguin ben organitzats i connectats de manera segura per evitar desconnexions accidentals o danys.

6. Solució De Problemes

If you encounter issues with your DIGITUS DN-95351 switch, consider the following troubleshooting steps:

• Sense energia: Verify the power cable is securely connected to both the switch and the power outlet. Check if the power switch on the rear panel is in the 'On' position. Test the power outlet with another device.
• Sense connectivitat de xarxa: Ensure Ethernet cables are properly connected to both the switch and the devices. Check the link/activity LEDs on the switch ports; a solid or blinking green light indicates a valid connection and activity. Verify IP configurations on connected devices.
• El dispositiu PoE no s'encén: Confirm the connected device is PoE/PoE+ compatible. Check the PoE status LEDs on the switch. Ensure the total power budget of 380W is not exceeded. Try connecting the device to a different PoE port.
• Rendiment de xarxa lent: Check for excessive network traffic or loops (Spanning Tree Protocol should prevent this). Verify cable integrity. Consider optimizing QoS settings if specific applications require priority.
• Accés a la interfície de gestió: Ensure your computer is on the same network segment as the switch. Verify the switch's IP address and your computer's network settings. Try resetting the switch to factory defaults if you cannot access it (refer to the full manual for reset procedures).

If problems persist, consult the detailed product data sheet or contact DIGITUS technical support.
