1.10 Remote System Management Logic
The remote system management logic consists of two major elements:
the System Power Controller (SPC), used to monitor and control system
power supplies, regulators, and cooling apparatus; and the Remote
Management Console (RMC), which facilitates remote interrogation
and control of the system. The components used within the remote
system management logic are powered by the AUX_5V supply, which is
always present whenever AC input power is available to the system.
