2.3 Connexió del commutador
- Connectar l'alimentació: Plug the power cord into the switch's power input and then into a grounded electrical outlet. The Power LED on the front panel should illuminate.
- Connectar dispositius de xarxa: Connect your network devices (computers, printers, servers, routers, etc.) to any of the 16 Ethernet ports on the front panel using standard Ethernet cables. The Link/Act LED for each connected port will light up, indicating an active connection. It will blink to show network activity.
- Verifica les connexions: Ensure all connected devices are powered on and their network adapters are enabled. The switch will automatically detect the speed and duplex mode of each connected device.
3. Funcionament
The Cisco SG100-16 is an unmanaged switch, meaning it operates without requiring any user configuration. Once connected, it automatically facilitates network communication between connected devices.
3.1 Encès/Apagat
To power on the switch, connect it to a power source. There is no dedicated power button. To power off, disconnect the power cord.
3.2 Indicadors LED
El panell frontal inclou indicadors LED que proporcionen informació d'estat:
- LED PWR (alimentació):
- Verd sòlid: L'interruptor està encès i funciona amb normalitat.
- Apagat: L'interruptor està apagat o no rep alimentació.
- Link/Act (Link/Activity) LEDs (per port):
- Verd sòlid: S'ha establert un enllaç de xarxa vàlid al port.
- Verd intermitent: Les dades s'estan transmetent o rebent a través del port.
- Apagat: No device is connected, or the connected device is powered off/has no link.
3.3 Qualitat de servei (QoS)
The SG100-16 switch supports Quality of Service (QoS) to help prioritize network traffic. This feature automatically identifies and prioritizes delay-sensitive traffic, such as voice and video, to ensure smooth performance even during periods of high network utilization. No user configuration is required for this function.
4. Manteniment
The Cisco SG100-16 switch is designed for reliable, low-maintenance operation. Regular maintenance is minimal.
- Neteja: Periodically clean the exterior of the switch with a soft, dry cloth. Do not use liquid or aerosol cleaners. Ensure ventilation openings are free from dust accumulation.
- Actualitzacions de firmware: As an unmanaged switch, firmware updates are typically not user-installable or required. If a critical update is released by Cisco, consult the official Cisco support weblloc per obtenir instruccions.
- Condicions ambientals: Ensure the switch remains within its specified operating temperature and humidity ranges to prolong its lifespan.
5. Solució De Problemes
This section provides solutions to common issues you might encounter with your SG100-16 switch.
5.1 Sense poder
- Símptoma: The PWR LED is off.
- Solució:
- Ensure the power cord is securely connected to the switch and a working electrical outlet.
- Verifiqueu que la presa de corrent funciona connectant-hi un altre dispositiu.
5.2 No hi ha llum d'enllaç en un port
- Símptoma: The Link/Act LED for a connected device is off.
- Solució:
- Ensure the Ethernet cable is securely plugged into both the switch port and the device.
- Prova un cable Ethernet diferent per descartar un cable defectuós.
- Verify the connected device is powered on and its network adapter is enabled.
- Proveu de connectar el dispositiu a un port diferent de l'interruptor.
- Reinicieu el dispositiu connectat.
5.3 Rendiment de xarxa lent
- Símptoma: Data transfer speeds are slower than expected.
- Solució:
- Ensure all connected devices and cables support Gigabit Ethernet (Cat5e or Cat6 cables are recommended for Gigabit speeds).
- Comproveu si hi ha trànsit de xarxa excessiu o aplicacions que consumeixen molta amplada de banda i que s'executen en dispositius connectats.
- Verify that the Link/Act LEDs are solid green (indicating a Gigabit connection) rather than amber (which might indicate a 10/100 Mbps connection on some switches, though this model uses green for both link speeds).
- Isolate the issue by testing performance with fewer devices connected.
5.4 Connectivitat intermitent
- Símptoma: Network connection drops sporadically.
- Solució:
- Comproveu totes les connexions dels cables per si hi ha fluïdesa o danys.
- Ensure the switch is placed in a well-ventilated area to prevent overheating.
- Test with different cables and devices to pinpoint the source of the intermittency.
- Consider potential sources of electromagnetic interference (EMI) near the switch or cables.
