6. Setup Guide
Follow these steps to set up your Real HD SW8-25G-MGV2 switch:
- Unpack the Switch: Carefully remove the switch and all accessories from the packaging.
- Placement: Place the switch on a stable, flat surface or mount it in a suitable location. Ensure adequate ventilation around the device.
- Connect Power: Connect the provided power adapter to the DC 12V 1A power input port on the switch and then plug the adapter into a power outlet. The RWR LED indicator should light up.
- Connect Network Devices:
- For 2.5G RJ45 Ports: Connect your computers, servers, NAS, WiFi 6 APs, or other network devices to any of the 8 RJ45 ports using CAT6 or higher Ethernet cables. The corresponding Link/Act LED will illuminate to indicate a successful connection and activity.
- For 10G SFP+ Port: Insert the included 10Gb SFP+ to RJ45 copper module into the SFP+ port. Then, connect a CAT6A/CAT7 Ethernet cable from the module to your 10G-capable device (e.g., server, another switch, or network card).
- Verify Connections: Check the Link/Act LEDs on the switch for each connected port. A solid green or yellow light indicates a successful link, and flashing indicates data transmission.

7. Operating Instructions (Web Management)
The Real HD SW8-25G-MGV2 is a managed switch, allowing for advanced configuration via a web-based interface.
- Initial Access:
- Ensure your computer is connected to the switch via an Ethernet cable.
- Set your computer's IP address to be in the same subnet as the switch's default IP. The default IP address of the switch is 192.168.2.1. For example, you can set your computer's IP to 192.168.2.10 with a subnet mask of 255.255.255.0.
- Open a web browser (e.g., Chrome, Firefox) and enter the default IP address
http://192.168.2.1in the address bar. - When prompted, enter the default login credentials:
Username:admin
Password:admin
- Configuration Options: Once logged in, you can access various management features:
- VLAN (Virtual Local Area Network): Configure VLANs to segment your network for improved security and performance.
- QoS (Quality of Service): Prioritize network traffic for critical applications (e.g., VoIP, video streaming) to ensure smooth operation.
- Security: Manage MAC address filtering, port security, and other security settings.
- Multicast: Configure IGMP Snooping for efficient multicast traffic management.
- MAC Address Table: View and manage the MAC address table.
- Link Aggregation (LACP/Static): Combine multiple physical links into a single logical link for increased bandwidth and redundancy. For Static Link Aggregation with NAS, select "Balance XOR".
- Spanning Tree Protocol (STP): Prevent network loops and provide path redundancy.
- Change Default Credentials: For security purposes, it is highly recommended to change the default username and password immediately after the first login.
