About Tellabs
2 distinct Tellabs models are covered.
Reaching the login page
Point a browser at whatever your computer reports as its default gateway. On Windows that is the Default Gateway line from ipconfig; on macOS, Network settings shows it under the active connection.
What the Tellabs defaults look like
Usernames vary; root is the one that appears most, on a single entry.
If the Tellabs password has already been changed
There is a recessed reset button on the back or underneath that needs a straightened paperclip. Hold it in for thirty seconds with the unit powered on. Let go when the lights change pattern, and give it a couple of minutes to come back up.
A reset clears more than the password. The Wi-Fi name and key go back to what is printed on the label, port forwards and firewall rules are discarded, and any static addressing is lost. Photograph the settings pages first — it takes two minutes and saves an evening.
