4. Setup Guide
4.1 Physical Installation
The DGS-1210-28P 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.
- Place the switch on a flat, stable surface with adequate ventilation.
Rackmount Installation:
- Attach the two rackmount brackets to the sides of the switch using the provided screws.
- Secure the switch into a standard 19-inch equipment rack using appropriate rack screws (not included).
Grounding the Switch:
For safety and proper operation, the switch must be properly grounded. Locate the grounding screw on the rear panel of the switch.
- Connect one end of a grounding cable (not included) to the grounding screw.
- Connect the other end of the grounding cable to a suitable grounding source, such as a grounded rack or building ground.

4.2 Connecting Devices
- Power Connection: Connect the AC power cord to the power input on the rear panel of the switch and then to a power outlet.
- Network Devices: Connect network devices (computers, servers, access points, IP cameras) to the RJ45 ports (1-24) using standard Ethernet cables. For PoE-powered devices, ensure they are compatible with 802.3af/at standards.
- Uplink Connections: Use the SFP ports (25-28) for high-speed fiber uplinks to other switches or network segments. Insert compatible SFP transceivers (not included) into the SFP slots, then connect fiber optic cables.
5. Operating Instructions
5.1 Power On
After connecting the power cord, the switch will automatically power on. The Power LED on the front panel will illuminate to indicate that the switch is receiving power.
5.2 LED Indicators
The front panel LEDs provide status information:
- Power LED: Indicates power status.
- Link/Act LED (per port): Solid green indicates a valid network link. Blinking green indicates network activity.
- PoE LED (per PoE port): Indicates PoE power status.
6. Management and Configuration
The DGS-1210-28P is a Smart Managed Switch, configurable via a web-based graphical user interface (GUI).
6.1 Accessing the Web GUI
- Connect a computer to any of the switch's RJ45 ports.
- Configure your computer's IP address to be in the same subnet as the switch's default IP address (refer to the Quick Installation Guide for default IP).
- Open a web browser and enter the switch's IP address.
- Log in using the default username and password (refer to the Quick Installation Guide).
6.2 Key Configuration Areas
Within the web GUI, you can configure various network settings:
- VLANs: Create and manage Virtual Local Area Networks for network segmentation.
