3. Verify that the SYS LED on the front panel illuminates, indicating the device is receiving power.

4.3 Tilslutning af netværkskabler

• RJ45-porte: Connect standard Ethernet cables from your network devices (computers, servers, other switches) to the 8x GbE RJ45 ports.
• SFP+ porte: Insert compatible SFP+ transceivers into the 2x SFP+ ports, then connect fiber optic cables to the transceivers for high-speed uplinks or downlinks.
• Konsolport: For initial configuration or advanced troubleshooting, connect a serial cable from your computer to the CONSOLE port.

5. Indledende konfiguration

5.1 Adgang til Web Brugergrænseflade (Web UI)

The GWN7811 can be managed via a web-baseret grafisk brugergrænseflade (GUI).

1. Connect a computer directly to any of the GWN7811's RJ45 ports.
2. Ensure your computer's IP address is in the same subnet as the switch's default IP address (e.g., 192.168.1.x). The default IP address for the GWN7811 is typically 192.168.1.1.
3. Åbn a web browser and enter the switch's default IP address (e.g., http://192.168.1.1) i adresselinjen.
4. Enter the default username and password (refer to the Quick Installation Guide or device label for default credentials).
5. Når du har logget ind, får du adgang til Web UI for further configuration.

5.2 Grundlæggende netværksindstillinger

After logging in, it is recommended to configure basic network settings:

• Skift standardadgangskode: Af sikkerhedsmæssige årsager skal du straks ændre standardadministratoradgangskoden.
• IP-adressekonfiguration: Configure a static IP address for the switch that is suitable for your network environment, or enable DHCP client if applicable.
• Systemtid: Set the correct system time and configure NTP (Network Time Protocol) for accurate time synchronization.

6. Betjeningsvejledning

The GWN7811 is a Layer 3 managed switch, offering advanced features for network control and optimization.

6.1 Layer 3 Features

• Statisk routing: Konfigurer statiske ruter til at dirigere trafik mellem forskellige IP-undernet.
• Inter-VLAN Routing: Enable routing between configured VLANs to allow communication across different broadcast domains.
• DHCP Server/Relay: The switch can act as a DHCP server for connected devices or relay DHCP requests to an external server.

6.2 VLAN-konfiguration

Virtual Local Area Networks (VLANs) segment your network into logical broadcast domains, improving security and performance.

1. Naviger til VLAN-sektionen i Web UI.
2. Create new VLANs by assigning a VLAN ID and name.
3. Assign ports to specific VLANs as either access ports (for end devices) or trunk ports (for connecting to other switches).

6.3 Servicekvalitet (QoS)

QoS allows you to prioritize network traffic, ensuring critical applications receive sufficient bandwidth.

• Configure QoS policies based on port, VLAN, IP address, or DSCP values.
• Apply bandwidth control to limit or guarantee bandwidth for specific traffic types.
