Lucent Technologies -48V CPS4000/CPS4000 PLUS Cabinet Power System
2 - 16 Product Description Issue 13 December 2000
Module Compatibility
Overview The flexibility of the -48V CPS system is based on the ability to mix
physically similar modules in the same shelf assembly. These modules
are keyed to prevent incompatible modules from being installed in the
same shelf. As an additional aid, labels on the modules are coded using
symbols, colors, and alpha-numeric designations to allow a visual check
of module compatibility.
Keying System The keying system depends on coded keying brackets installed in the
power modules and corresponding keying strips installed in the shelf
assemblies. Control units are keyed using tabs on the control unit circuit
pack and pins on the keying strip.
Symbols Symbols on module labels indicate each module's input and/or output
and its functional classification. Colors indicate compatible voltages,
and alpha-numeric codes are used to show voltage and current levels as
well as functional classifications.
