The NEC follows the IBC rather closely these days and it doesn't' go into how a rack should be mounted or not. Codes like the NEC never tells you when you have to do something, it only states how it is to be done. There are other NFPA codes that will tell you the when part.
As for the BICSI, I don't think it covers the mounting requirements of when a rack needs to be hard mounted or not. I need to dig out my copy of the BICSI’s Information Technology Systems Installation Methods Manual (ITSIMM) to be sure.
The best thing to do is just contact your AHJ and see what they require.
