XTS4000 basic disassembly, also crypto modules

[mab]

Does anyone know where I can find the basic service manual for the XTS-4000? When I log in to MOL I can find PDFs for the user manual and the detailed service manual, but not the basic service manual (which, hopefully, has the basic assembly and disassembly procedures, etc).

More to the point, I have two XTS-4000s, and I'd like to move the crypto module from one into the other (the one I want to use with crypto is on the wrong band). Both are flashed for HW multi-key. But I'm not sure how to safely remove and install the module, or, for that matter, whether the module is actually even on a separate removable board as it is on the XTS5000s.

Anyone with any experience with the XTS4000 hardware?

Thanks!
