Is there a procedure that show how to do it step by step?
VMware has a KB article dedicated to your question in ESX:

Or if you are on ESX 4.0 Update 2, you can use this:

If you're running ESXi version 4.X, you can simply connect to the console and use the DCUI (Press F2 to customize the system) and set the management IP from there.
