Thanks. I did look there first.
I feel like an idiot, but I can't find a link or button on any page that leads to the admin page. I've tried two different browsers (Safari and Firefox).
Note that your instructions say that the login credentials are root/root. When I got my M10, it defaults to a user name of admin. I ended up guessing that the password was also admin. That was the only way that I could get in.
When I try entering root/root, it gives me an "Invalid username and/or password" error. I can only log in via admin/admin.
If there are separate root and admin users, then perhaps the fact that I can only login as admin means that I have reduced privileges. That might explain why I can't see the admin page. This assumes that the web GUI is different for different privileges, which is just a guess on my part.
Anyway, this machine is behind a firewall in a locked rack in a secure data center with no WiFi access. While I prefer to change the default password, it's unlikely to be a real security issue. So maybe I shouldn't stress over the password.
I am getting an m10 on Monday. I will look for the page for you.
m10's have different firmware yours may not work.
