E1406-1 : Set the Command Module as Resource Manager
Set the Command Module as resource manager by setting its logical address
to 0. (The Command Module’s factory-set logical address is 0.)
At power-on, the resource manager function is started. The purpose of the
resource manager is to:
identify all plug-in modules installed in the C-size mainframe
set commander/servant hierarchies whereby one or more plug-in
modules control other plug-in modules
perform A24/A32 address mapping so that modules requiring
additional addressing can receive it
allocate interrupt lines to manage communication between interrupt
handler modules and interrupter modules
start system operation
Once the power-on sequence is completed and the system is started, the
resource manager is no longer used. See Appendix A, "Terms and
Definitions," for more information on the resource manager.
