Well since it's been a year you probably don't really care about what's stored on your server, at this point you should probably attempt a factory reset on your server which will put it back into the state it was when you got it:
You will need the Server Recovery Disc which came with your server, and a paperclip.
To start with, you must place the server into recovery mode. To do this, turn the server off. When you turn it back on, wait until the health light begins to alternate between blue and red. This only occurs for a few seconds while the server is booting.
While it is alternating between those two colours, use your paper clip to press the reset button located next to the USB port on the front of the server.
On an EX470, the light should start to alternate between purple and red instead of blue and red once it's in recovery mode. (**NOTE** Sometimes it can be hard to see whether it's purple, all it is really doing is turning on the blue LED while the red is
still on, so that it looks purple. So if you're viewing it from a weird angle, it may still look blue instead of purple.)
After you have done this, place the recovery disc into a PC on the same network as the server. This should start the recovery wizard. Progress through the wizard and it will begin searching for the server. As long as it is able to find the server in recovery
mode, it will prompt you to perform either a server recovery or a factory reset.
Up to you at this point if you want to do a server recovery or factory reset, if you do a server recovery and it's succesful your server should get setup, and you should get access again to the data on your server, if you select Factory Reset it will wipe
out everything on the server, and bring it back to factory defaults.
(I've never done this before myself, but these instructions also came with your server)
