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. 전원 연결하기

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. 전면 패널의 전원 LED가 켜지면 스위치에 전원이 공급되고 있음을 나타냅니다.

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. 초기 구성 접근

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. 컴퓨터를 스위치의 RJ45 포트 중 하나에 연결하십시오.
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. 열기 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. 스위치 작동

3.1. 기본 동작

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.

• 녹색 LED (점등): Indicates a valid network link.
• 녹색 LED(깜박임): 네트워크 활동(데이터 전송)을 나타냅니다.
• 끄다: 링크 또는 연결이 없습니다.

3.2. Web- 기반 관리

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

• VLAN 구성: 네트워크 트래픽을 분할하기 위해 가상 근거리 통신망(VLAN)을 생성하고 관리합니다.
• 서비스 품질(QoS): 최적의 성능을 보장하기 위해 중요한 네트워크 트래픽(예: 음성, 비디오)에 우선순위를 부여하십시오.
• 링크 집계: 여러 개의 물리적 링크를 하나의 논리적 링크로 결합하여 대역폭과 중복성을 높입니다.
• 보안 기능: Configure Access Control Lists (ACLs), 802.1X authentication, and ARP Spoofing Prevention.
