Intel® Server System S7000FC4UR TPS
(One supply present AND ((CB_Type=Japan/Brazil AND Util = 74%) OR (CB_Type = Not
Japan/Brazil) AND Util = 90%))
Normal operation mode occurs when a single power supply or both power supplies are present
(redundant mode) and functioning. When utilization limits are crossed, the BMC is informed
through the shifty bus bit. When two power supplies are present the BMC will check for
PS_ACGOOD signals (through PSMI) and allow the system to continue running if both power
supplies are functional. If either supply is not functional, or if a single power supply has crossed
its utilization limit, the BMC will check whether the supply is low line (100VAC: AC_RANGE = 0),
in which case processors will be throttled through FORCE_PR#.
2.2.18.5 Miscellaneous Functions
Clock divider- the 32KHz clock input (SUSCLK) will be divided down into a 500Hz clock
to be used in delays and a counter throughout the code.
Debounce circuits- based on previous platforms, power supply PWROK signals and
PRES signal require debounce functionality to avoid glitches.
CPU_SKTOCC – 4 input NAND output using the 4 CPU#_SKTOCC signals going to
PS_ON_N logic.
