dell powerconnect 3524p no command line

I have a dell powerconnect 3524p. I have watched it boot in the terminal screen. It goes through it's boot process, showing pass on the checks it makes. When it's done booting, it shows standalone mode, and that's it. There is no command line (>), there is just a green square. I hit enter, or hit any other key and it does nothing.

Any help on this would be greatly appreciated.

Thanks in advance,
