Lantronix Default KVM Passwords

Lantronix makes device servers and console servers that put serial equipment on a network. The Lantronix records here run across the SCS- and ETS- lines.

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.

sysadmin is the username on 4 of the 17 entries. 11 of them ask for no username at all. 5 of them shipped with no password at all.

Where one is set, access comes up most often, on 3 entries. There are 7 different passwords across the Lantronix set, so check your exact model rather than assuming. 2 of them are reached over a protocol that puts the password on the wire in clear text, so work from a machine on the same wired network rather than across the internet, and change the password once you are in.

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.
