1. Introduktion
This manual provides essential information for the installation, operation, and maintenance of the PHOENIX CONTACT FL WLAN 4321 Wireless Ethernet Bridge, model 1194423. This pre-paired wireless bridge system is designed to extend Ethernet networks wirelessly over distances up to 2 miles, offering a reliable 300 Mbps connection. It utilizes Passive POE for simplified power and data transmission.
2. Produktet er slutview
The FL WLAN 4321 system consists of two pre-configured wireless Ethernet bridge units, enabling a point-to-point wireless connection. These units are ideal for applications requiring robust and long-range network extension without the need for complex cabling. The Passive POE capability allows for flexible installation by delivering power and data over a single Ethernet cable.

Figure 2.1: The PHOENIX CONTACT FL WLAN 4321 Wireless Ethernet Bridge units. The image displays two identical white rectangular devices, positioned vertically next to each other. Each unit has a label on its side, indicating "FL WLAN 4321" and a letter (A or B) for identification.

4. Sikkerhedsoplysninger
Overhold følgende sikkerhedsforanstaltninger for at forhindre skader på enheden eller personskade:
- Sørg for korrekt jordforbindelse for alle elektriske forbindelser.
- Udsæt ikke enheden for ekstreme temperaturer, fugt eller direkte sollys.
- Avoid placing the device near strong electromagnetic fields.
- Only use the provided power adapters and cables.
- Installationen skal udføres af kvalificeret personale i overensstemmelse med lokale el-forskrifter.
5. Opsætning
The FL WLAN 4321 units are pre-paired for ease of installation. Follow these steps for initial setup:
- Identificér enheder: Unpack both bridge units. They are typically labeled 'A' and 'B' or similar for easy identification of the master and client roles, though they are pre-paired to function together.
- Montering: Choose suitable mounting locations for each unit. For optimal performance, ensure a clear line of sight between the two units. Mount them securely using appropriate hardware (not included).
- Tilslut Ethernet-kabler:
- Connect one end of an Ethernet cable from your network device (e.g., router, switch) to the "LAN" port on the Passive POE Injector.
- Connect the other end of the Ethernet cable from the "POE" port on the Passive POE Injector to the Ethernet port on the Wireless Ethernet Bridge unit.
- Tilslut strøm: Plug the power cord into the Passive POE Injector and then into a suitable power outlet. The bridge unit will power on via the Ethernet cable.
- Bekræft forbindelsen: Once both units are powered on and connected, observe the LED indicators. A solid link LED on both units typically indicates a successful wireless connection between them. Refer to the "Operating Instructions" section for LED status meanings.
- Netværkskonfiguration: Ensure your network devices connected to the bridges are configured correctly (e.g., IP addresses, subnet masks) to communicate across the wireless link.
6. Betjeningsvejledning
Once installed and powered, the FL WLAN 4321 units operate automatically as a transparent wireless Ethernet bridge. Data transmitted on one side of the bridge will be wirelessly relayed to the other side.
LED-indikatorer:
| LED navn | Status | Beskrivelse |
|---|---|---|
| Power LED | Solid grøn | Enheden er tændt. |
| LAN-LED | Solid grøn | Ethernet-forbindelse etableret. |
| LAN-LED | Blinkende grønt | Dataaktivitet på Ethernet-porten. |
| WLAN LED | Solid grøn | Wireless link established between units. |
| WLAN LED | Blinkende grønt | Data activity over wireless link. |
7. Vedligeholdelse
Regular maintenance helps ensure the longevity and optimal performance of your wireless Ethernet bridge.
- Rensning: Gently wipe the exterior of the units with a soft, dry cloth. Do not use liquid cleaners or aerosols.
- Firmwareopdateringer: Periodically check the PHOENIX CONTACT website for available firmware updates. Applying updates can improve performance, add features, or address security vulnerabilities. Follow the instructions provided with the firmware update package carefully.
- Miljøtjek: Ensure the operating environment remains within specified temperature and humidity ranges. Keep the area around the units clear to allow for proper ventilation.
8. Fejlfinding
If you encounter issues with your FL WLAN 4321 system, refer to the following common problems and solutions:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm (strøm-LED slukket) | No power from POE injector or power outlet. | Check power cord connection to POE injector and wall outlet. Ensure the POE injector is functioning. Verify Ethernet cable from POE injector to bridge unit is securely connected. |
| No Wireless Link (WLAN LED Off) | No line of sight, excessive distance, interference, or unit malfunction. | Ensure clear line of sight between units. Reduce distance if possible. Check for sources of interference (e.g., large metal objects, other wireless devices). Power cycle both units. |
| No Ethernet Link (LAN LED Off) | Faulty Ethernet cable or connected device. | Verify Ethernet cable connection to the bridge unit and the connected network device. Try a different Ethernet cable. Test the connected network device. |
| Langsom forbindelseshastighed | Interference, signal degradation, or network congestion. | Optimize unit placement for better signal strength. Minimize sources of interference. Check for network congestion on your wired network. |
