How to Change IP Address of EDFA?

Option 1: Change IP Address via Touchscreen LCD

For on-site technicians, the most direct method is using the high-responsivity touch interface. Premlink, as a leading EDFA factory, integrates a PIN-protected security layer to prevent unauthorized or accidental network changes.

  1. Access Network Settings: Power on your Premlink EDFA and tap the “Network” icon on the main menu.
  2. Enter PIN Interface: Tap “IP Address”. To ensure carrier-grade security, the system will prompt for a PIN code.
  3. Authorization: Input the default PIN “1111”. (Note: The default authorization timeout is 5 minutes. If there is no activity for 5 minutes, you must re-enter the PIN).
  4. Modify & Save: The current IP (e.g., 192.168.2.1) will appear. Use the on-screen digital keyboard to input your new desired address (e.g., 192.168.1.1) and hit save.

Option 2: Change IP Address via Web Browser (Web GUI)

If you are managing the device from a control room, the Web GUI offers a more comprehensive interface. Follow these industrial-standard steps for a successful handshake between your laptop and the EDFA:

  1. Hardware Connection: Connect an RJ45 Ethernet cable from the EDFA’s management port to your laptop. Ensure the EDFA is powered on and receiving input power to generate real-time data.
  2. Match Network Segments: Set your laptop’s static IP to the same subnet as the EDFA.
    • EDFA Default IP: 192.168.1.1
    • Laptop Static IP: 192.168.1.x (where x is any number from 2 to 255).
  3. Login to Web GUI: Open a browser (Chrome/Edge recommended) and enter 192.168.1.1. Input your credentials to enter the homepage.
  4. Network Re-configuration: Navigate to Network -> IP Address. Enter your new gateway and IP details, then apply the changes.

💡 Pro-Tip from the Factory: After changing the IP via Web GUI, you may lose the connection immediately as the device migrates to the new address. Simply update your browser’s URL to the new IP to resume monitoring.

FAQ: Troubleshooting Your EDFA Network Setup

Q1: What if I forgot my custom PIN code?
A: If the default “1111” has been changed and lost, please contact our EDFA factory technical support with your device serial number (S/N) for a master reset code.

Q2: Why can’t I ping the EDFA even with the correct IP?
A: Check your firewall settings and ensure the RJ45 cable is a standard Cat5e or Cat6. Also, verify on the Touch LCD that the IP shown matches the one you are trying to ping.

Q3: Can I change the PIN and Timeout duration?
A: Yes, these security parameters are fully customizable within the Web GUI under the System/Security tab to meet your ISP’s local security protocols.
