I think we'll need more information than that. What happens when you try to boot it?– ForeverWintrApr 26, 2013 at 5:38

well I logged as root and just typed 'reboot'. Then message "system goes down for reboot" showed and didn't go up after this.. that's it.– Jason PaddleApr 26, 2013 at 5:41

What does "didn't go up" mean?– ForeverWintrApr 26, 2013 at 5:42

1Found the problem. Was it between the server and the switch and the speed between. Need to set speed to 1000Mbits, duplex to full and turn off auto negotiation.– Jason PaddleApr 26, 2013 at 7:01

2Because your question is impossible to answer. There are hundreds of reasons why a server might not reboot correctly, it is impossible to know which is the case from the information you have given. All we know is what you tell us and all you told us is "did not reboot".– terdonApr 26, 2013 at 10:31

If you have physical access to the machine or a KVM, hook up a monitor and observe the most recent output. It's possible that the system experienced a kernel panic or a generic boot failure and is standing by whilst still powered on. If nothing is displayed, try a cold reboot and check for any output during the POST and boot sequences
