Have you looked it up in your Systems manual? Siemens has excellent references on the Internet [1]. There are details in table 8-1 (S7-200. Programmable Controller, System Manual, page 249). This troubleshooting table indicates many of the possible problems that would cause the System Fault (SF) LED to be lit.
If you have a different S7 model I am sure that the reasons for the error would be the same.
