Modifying the IP address of the fiber optic switch
You can change the IP address of a fiber optic switch either via its web interface, CLI, or vendor-specific management tools, depending on the switch model.
Using the Web Interface
Most managed fiber optic switches allow IP configuration through a web browser:
- Connect your computer to the switch using an Ethernet cable.
- Ensure your computer is on the same subnet as the switch's current IP.
- Open a web browser and enter the switch's IP address (e.g., 192.168.1.1 or 192.168.88.1 for MikroTik devices) in the address bar .
- Log in using the default credentials (often
adminwith no password or as specified on the device label), . - Navigate to System Settings or Network Settings.
- Change the IP address to a unique static IP within your network range.
- Apply the changes. Note that the session will disconnect, and you must reconnect using the new IP .
Using DHCP
If the switch supports DHCP:
- You can configure the switch to obtain an IP automatically from a DHCP server.
- Alternatively, assign a specific IP via DHCP reservation based on the switch's MAC address to ensure it always receives the same IP .
Using CLI (Command Line Interface)
For switches that support CLI access:
- Connect via console/serial cable or SSH/Telnet if the current IP is reachable .
- Enter terminal configuration mode.
- Navigate to the interface configuration for the management VLAN or port.
- Assign the new static IP and subnet mask.
- Save the configuration to ensure it persists after reboot .
Vendor-Specific Tools
- MikroTik FiberBox: Use the Winbox utility to connect to the default IP (192.168.88.1) and change the IP address under the network settings .
- EdgeSwitch: Use the web GUI after connecting to the fallback IP (192.168.1.2) to set a new static IP .
Important Considerations
- Always ensure the new IP is unique within your network to avoid conflicts.
- If changing to an IP outside the current subnet, a console connection is recommended to maintain access during the change .
- After changing the IP, update any network documentation and reconnect using the new address. By following these steps, you can successfully change the IP address of your fiber optic switch, whether using a web interface, CLI, or vendor-specific management tool.
