The power supply must provide a 5V Standby power source for the platform to provide any
management functionality. 5V Standby is a low power 5V supply that is active whenever the
system is plugged into AC power. 5V Standby is used by the following onboard management
devices:
•
Management Controller (BMC and/or mBMC) and associated RAM, Flash, and
SEEPROM which are used to monitor the various system power control sources
