Hi all, I hope it's ok to post this here as the xserve has similar hardware to the Mac pro and there's no xserve forum. I just bought a used xserve, 2006 2.0Ghz quad core. I just hooked it up to make sure it worked okay. It has no hard drive, I just wanted to see if it would fire up. Well it turns on and looks like it's running, but there's no picture on the screen at all. I know the monitor works. I am not sure if xserves "chime" or not. But if it is supposed to, it doesn't. All the fans are running at full blast which I presume it should be without an OS installed. I would figure it would boot up with a question mark. Do these things need a hard drive to be installed in in order to function properly? Hopefully one of you has more experience with one of these things than I do, I was under the impression that it should be just like setting up a Mac pro.
