Between Bays
An LMS Network cable must be installed between all bays with LMS CPU circuit cards
installed, as detailed in the following procedure. Pre-assembled cables are available.
Refer to System Application Guide SAG582140000 for P/N's. The SAG can be accessed
via the CD (Electronic Documentation Package) furnished with your system. Refer to
