About Arescom
2 distinct Arescom 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. None of the Arescom entries here are for a web interface — they are reached over telnet and n/a, which means a terminal or a serial console rather than a browser.
What the Arescom defaults look like
None of them ask for a username; the field is left empty. One model shipped with no password at all. One of them is 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 Arescom password has already been changed
This is not hardware you reset with a paperclip. Recovery runs through the console port: interrupt the boot sequence, tell the bootloader to ignore the saved configuration, start up, read or clear the password, then save and reboot. The exact key sequence differs by platform and is in the vendor documentation under password recovery.
You need physical access and a serial cable for this, which is deliberate. Anything reachable only over the network cannot be recovered this way.
