5. Setup
5.1 Physical Installation
The AT-GS950/18PS V2 can be installed on a desktop or mounted in a standard 19-inch equipment rack.
- Desktop Installation: Attach the provided rubber feet to the bottom of the switch to prevent slipping and ensure proper ventilation. Place the switch on a flat, stable surface.
- Rack Installation: Use the included rack mount kit to secure the switch in a 19-inch equipment rack. Ensure adequate space for airflow around the unit.
Ensure the installation location is well-ventilated, free from excessive dust, and within the specified operating temperature and humidity ranges.
5.2 Network Connection
- Connect network devices (e.g., computers, servers, IP cameras, wireless access points) to the 10/100/1000BASE-T Ethernet ports (1-16) using standard Ethernet cables.
- For devices requiring power, ensure they are PoE or PoE+ compatible and connect them to the PoE+ enabled ports.
- For uplink connections to other network devices or the core network, use the SFP slots (17-18) with appropriate SFP transceivers and fiber optic cables.
5.3 Power On
- Connect the power cable to the AC inlet on the rear panel of the switch.
- Secure the power cable with the provided retention hook to prevent accidental disconnection.
- Plug the other end of the power cable into a suitable AC power outlet.
- The system will power on automatically. Observe the LED indicators on the front panel to confirm proper startup. The SYSTEM LED should turn green, and port LEDs will indicate link status and activity.
6. Operation
6.1 Web GUI Access
The switch can be managed via its web-based graphical user interface (GUI).
- Ensure your computer is connected to the switch via an Ethernet cable and is on the same network segment.
- Open a web browser (e.g., Chrome, Firefox, Edge).
- Enter the default IP address of the switch in the browser's address bar. (Refer to the product's quick start guide or default settings for the exact IP address, typically 192.168.1.1 or similar).
- Enter the default username and password when prompted. (These are usually provided in the quick start guide or on a label on the device).
- Upon successful login, you will access the Web GUI dashboard, where you can monitor and configure the switch.
6.2 Basic Configuration
The Web GUI allows for various configurations, including VLANs and QoS.
- VLAN Configuration: Navigate to the VLAN section to create, modify, or delete VLANs. Assign ports to specific VLANs to segment your network and improve security and performance.
- QoS Configuration: Access the QoS settings to prioritize network traffic. This is crucial for applications sensitive to latency, such as VoIP or video streaming, ensuring their smooth operation.
6.3 PoE+ Management
Monitor and manage Power over Ethernet Plus (PoE+) settings through the Web GUI.
- View the power consumption of connected PoE+ devices.
- Enable or disable PoE+ on individual ports.
- Set power priorities for ports to ensure critical devices receive power first in case of budget limitations.
