Sun Microsystems Default Router Passwords
This page lists 3 confirmed default credentials for Sun Microsystems equipment, covering 3 models. The pairing you are most likely to need is admin with admin.
Entries are reachable over http and adminsrv. 2 of these entries use a protocol that sends the password in clear text, so use them on a trusted network and change the password once you are in.

About Sun Microsystems
Sun Microsystems built servers, Solaris and the Cobalt appliance line before Oracle acquired it in 2010.
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 Sun Microsystems defaults look like
admin is the username on 2 of the 3 entries. Where one is set, admin comes up most often, on 2 entries. 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.
If the Sun Microsystems 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.
