The CSA (formerly known as the NSA) is a administration tool though ; you really should know what you are doing if you are accessing it!
You access it through a URL just like the application itself ; your system administrator should know the URL (it might just be the same URL you access the application from with a different port number at the end) - the right services must be running to do all this though ; its is entirely possible to be running the PPM application without the CSA service running!
