The HMC communicates with the CPC through the Support Element (SE). When tasks are
performed at the HMC, the commands are sent to one or more Support Elements which then
issue commands to their CPCs. CPCs can be grouped at the HMC so that a single command
can be passed along to as many as all of the CPCs defined to the HMC.
One Hardware Management Console can control up to 100 Support Elements, and one
Support Element can be controlled by 32 Hardware Management Consoles. Refer to the
examples shown in FigureA-1 and Figure A-2 on page 235 for typica l Hardware
Management Console configurations.
