Technical Product Specification
health of the power subsystem's component power supplies. The BMC implements Dynamic
Power Supply Redundancy status based upon current system load requirements as well as
total Power Supply capacity. This status is independent of the Cold Redundancy status. This
prevents the BMC from reporting Fully Redundant Power supplies when the load required by
the system exceeds half the power capability of all power supplies installed and operational.
Dynamic Redundancy detects this condition and generates the appropriate SEL event to notify
the user of the condition. Power supplies of different power ratings may be swapped in and
out to adjust the power capacity and the BMC will adjust the Redundancy status accordingly.
The definition of redundancy is power subsystem dependent and sometimes even
configuration dependent. See the appropriate Platform Specific Information for power unit
redundancy support.
This sensor is configured as manual-rearm sensor in order to avoid the possibility of
extraneous SEL events that could occur under certain system configuration and workload
conditions. The sensor shall rearm for the following conditions:
PSU hot-add

System reset

AC power cycle

DC power cycle

System AC power is applied but on standby – Power unit redundancy is based on OEM SDR
power unit record and number of PSU present.
System is (DC) powered on - The BMC calculates Dynamic Power Supply Redundancy status
based upon current system load requirements as well as total Power Supply capacity.
The BMC allows redundancy to be configured on a per power-unit-redundancy sensor basis
by means of the OEM SDR records.

Component Fault LED Control

Several sets of component fault LEDs are supported on the server board (see Figure 7). Some
LEDs are owned by the BMC and some by the BIOS.
The BMC owns control of the following FRU/fault LED:
Hard Disk Drive Status LEDs – The HSBP PSoC* owns the hardware control for these

LEDs and detection of the fault/status conditions that the LEDs reflect.
