server rebooting frequently how to diagnose

[Tapas Mishra]

I am having a small problem on my Power Edge server.
It is PowerEdge R710.
It is rebooting frequently I am having a virtuallization setup over it.
Some one a long time back had told  me about some way to make a log on
power edge via a utility which can have some sort of dumps.
Which I can send to Dell for analysis if any one is able to understand
what I am saying then give me a link.
Or if there is some other way to debug this?
