2. Setup and Installation

2.1. Package Contents

Verify the package contains the DGS-1210-20 switch, a power cord, and any included accessories such as rack-mount brackets or rubber feet.

2.2. Physical Installation

The DGS-1210-20 can be installed on a desktop or mounted in a standard 19-inch equipment rack.

• Desktop Installation: Attach the included rubber feet to the bottom of the switch to prevent scratching and provide stability. Place the switch on a flat, stable surface.
• Rack Installation: Secure the provided rack-mount brackets to the sides of the switch using the screws. Mount the switch into an open slot in a standard 19-inch equipment rack.

Ensure adequate ventilation around the switch to prevent overheating. Maintain at least 10 cm (4 inches) of clear space around the ventilation openings.

2.3. Connecting Power

1. Connect one end of the AC power cord to the power inlet on the rear panel of the switch.
2. Connect the other end of the AC power cord to a suitable power outlet.
3. The Power LED on the front panel will illuminate, indicating the switch is receiving power.

2.4. Connecting Network Devices

Use standard Ethernet cables (Cat5e or higher) to connect network devices (e.g., computers, servers, other switches) to the RJ45 ports on the front panel. For fiber optic connections, insert compatible SFP transceivers into the SFP ports and connect fiber optic cables.

• Connect devices to any of the 16 Gigabit RJ45 ports.
• For fiber uplinks or long-distance connections, use the 4 Gigabit SFP ports with appropriate SFP modules and fiber cables.

2.5. Initial Configuration Access

The DGS-1210-20 switch can be managed via a web-based graphical user interface (GUI). By default, the switch obtains an IP address via DHCP. If no DHCP server is available, it will use a default static IP address (e.g., 10.90.90.90).

1. Connect a computer to any of the switch's RJ45 ports.
2. Ensure your computer's IP address is in the same subnet as the switch (e.g., if the switch is 10.90.90.90, set your computer to 10.90.90.100).
3. Open a web browser and enter the switch's IP address (e.g., http://10.90.90.90).
4. Log in using the default credentials (refer to the product documentation for specific default username and password).

3. Operating the Switch

3.1. Basic Operation

Once powered on and connected, the DGS-1210-20 switch automatically begins forwarding Ethernet frames between connected devices. The Link/Act LEDs for each port indicate connection status and activity.

• Green LED (Solid): Indicates a valid network link.
• Green LED (Flashing): Indicates network activity (data transmission).
• Off: No link or connection.

3.2. Web-Based Management

The web-based management interface allows for comprehensive configuration and monitoring of the switch. Key functions include:

• VLAN Configuration: Create and manage Virtual Local Area Networks to segment network traffic.
• Quality of Service (QoS): Prioritize critical network traffic (e.g., voice, video) to ensure optimal performance.
• Link Aggregation: Combine multiple physical links into a single logical link for increased bandwidth and redundancy.
• Security Features: Configure Access Control Lists (ACLs), 802.1X authentication, and ARP Spoofing Prevention.
• System Monitoring: View port status, traffic statistics, and system logs.

3.3. Surveillance Mode

The DGS-1210-20 series supports a dedicated Surveillance Mode, which simplifies the deployment and management of IP surveillance networks. This mode automatically detects ONVIF-compliant devices and optimizes video traffic, enhancing security and efficient handling of surveillance data through automatic detection and segmentation.
