3. Танзим ва насб
The NICGIGA 18 Port Gigabit PoE+ Switch is designed for easy plug-and-play setup. No software configuration is required for basic operation.
3.1 Пайваст кардани коммутатор
- Пайвастшавӣ ба барқ: Plug the provided power adapter into the switch's power input port and then into a standard AC power outlet (110-240V). The power LED on the switch will illuminate.
- Пайваст кардани дастгоҳҳо:
- For PoE-compatible devices (e.g., IP cameras, IP phones, wireless access points), connect them to ports 1-16 using standard Ethernet cables. The switch will automatically detect and supply power to these devices.
- For non-PoE devices (e.g., routers, NVRs, printers, laptops), connect them to any available port (1-18) using standard Ethernet cables for data connectivity.
- Use ports 17 and 18 as uplink ports to connect to your router, NVR, or other network backbone devices for high-speed data transfer.

3.2 Васлкунии раф
The switch can be installed on a desktop or mounted in a standard 19-inch server rack using the included rack mount kit.
- Attach the two rack mount brackets to the sides of the switch using the provided screws.
- Secure the switch with the attached brackets into your 19-inch server rack using appropriate rack screws (not included).

4. Дастурҳои истифодабарӣ
4.1 Функсияи барқ тавассути Ethernet (PoE).
The switch supports IEEE 802.3af/at standards, automatically detecting and providing power to compatible Powered Devices (PDs) connected to ports 1-16. Each PoE port can deliver up to 30W, with a total power budget of 250W for all PoE ports.
4.2 Реҷаи VLAN
The NICGIGA GS1620P switch includes a One-Key VLAN mode. When activated, this mode isolates ports 1-16 from each other, preventing direct communication between devices connected to these ports. However, all ports (1-16) can still communicate with the uplink ports (17-18). This feature enhances network security and optimizes bandwidth utilization by segmenting traffic.

4.3 Нишондиҳандаҳои LED
LED-ҳои панели пеш маълумотро дар бораи ҳолати коммутатор ва портҳои он пешниҳод мекунанд:
- LED барқ: Ҳолати қудрати коммутаторро нишон медиҳад.
- LED-ҳои Link/Act (барои ҳар як порт): Indicates a network link and data activity on the respective port.
- LED-ҳои PoE (барои ҳар як порти PoE): Ҳолати интиқоли нерӯи PoE -ро нишон медиҳад.
5. Нигоҳдорӣ
To ensure optimal performance and longevity of your NICGIGA PoE+ Switch, follow these maintenance guidelines:
- Вентилятсия: Ensure proper airflow around the switch. Do not block ventilation openings.
- Тозакунӣ: Қисми берунии калидро мунтазам бо матои нарм ва хушк тоза кунед. Аз истифодаи тозакунандаҳои моеъ ё аэрозолӣ худдорӣ намоед.
- Муҳити зист: Operate the switch within its specified temperature and humidity ranges. Avoid exposure to direct sunlight, excessive heat, or moisture.
- Идоракунии кабелӣ: Keep network cables organized to prevent strain on ports and ensure efficient cooling.
6. Баррасии мушкилот
If you encounter issues with your NICGIGA PoE+ Switch, refer to the following common troubleshooting steps:
| Мушкилот | Сабаби эҳтимолӣ | Ҳалли |
|---|---|---|
| No power to switch | Адаптери барқ пайваст нест ё вайрон шудааст; мушкили розеткаи барқ. | Ensure power adapter is securely connected to both the switch and a working power outlet. Check the power adapter for damage. |
| No link/data activity on a port | Faulty Ethernet cable; device not properly connected; device issue. | Verify Ethernet cable connections. Try a different cable. Ensure the connected device is powered on and functioning correctly. |
| PoE device not receiving power | Device not PoE compatible; cable issue; total power budget exceeded. | Confirm the device is IEEE 802.3af/at compliant. Check the Ethernet cable. Ensure the total power consumption of all PoE devices does not exceed 250W. |
| Devices on ports 1-16 cannot communicate with each other | VLAN mode is enabled. | If direct communication between these ports is desired, disable VLAN mode using the switch on the front panel. |
