Looking to Identify Model; So I can purchase an adapter

I just picked up a used Apple Cinema HD Display.

I have searched all over the unit, and can't find a model number.

So I am trying to identify which one this is, so I can purchase a power supply for it...

Or at least get the proper manual so I know how to connect it.

The main video connector is a DVI, then has three others. USB, Firewire, and what appears to be a power connection.

But, my MacBook Pro doesn't have a matching connection for it.

All I have on the unit is a Serial Number: 2A5323UGPKL

Any help would be appreciated.
