<p>A system having replaceable subsystems is operable in a certified configuration after installation of a replacement subsystem. The system includes several subsystems each installed at an interface. For each subsystem, the interface includes memory having a description of the operating environment for that subsystem. The memory stores modules each having a signature, for example, a cyclic redundancy code (CRC). A method performed by a subsystem of the plurality includes, in any order, (a) obtaining data provided by the memory, the data comprising a multiplicity of respective pluralities of rows; (b) storing each respective plurality of rows so that all rows identified for each respective table may be accessed in series without accessing rows of any other than the respective table; and (c) communicating with other subsystems in accordance with rows of the tables. Each plurality of rows is identified for at least one particular table of a set of tables. There is no reference in the data from a first plurality of rows of the multiplicity identified for a particular table to a second plurality of rows of the multiplicity identified for the same table.</p> |
