PWR Payload Power.
This powers the host side of the board where the application software runs. It is
granted by the BMC or the SMC after all prerequisites are met. Prerequisites can be,
for example, a closed handle switch, power on the backplane etc.
SDR Sensor Data Record
This is the IPMI data structure that defines a sensor.
SDRR Sensor Data Record Repository
The SDRR is located in the BMC and contains all SDRs of the chassis’ boards that
are administrated. A free Linux utility named “ipmitool” makes a full chassis discovery
and fills the SDRR with the SDRs being found.
SEL System Event Log
The SEL is located in the BMC and keeps track of all events in the chassis. If an
event occurs on any board, the sensor event is sent through the IPMB bus to the
BMC, which additionally stores its own events as well.
SMBIOS System Management BIOS
SMC Satellite Management Controller
Each board is equipped with an IPMI controller acting either as a BMC or as an SMC.
In a CompactPCI chassis, there can be several SMCs. The SMC administrates the
sensor and FRU data of the CP6003-SA/RA/RC and makes it available to the BMC.
Each SMC can be connected to the BMC via a dedicated bus (IPMB-0). The CP6003-
SA/RA/RC’s IPMI controller can be configured to operate in SMC mode or in BMC
mode via an IPMI OEM command or an uEFI Shell command. The factory setting is
SMC.
SMS System Management Software (designed to run under the OS)
SOL Serial over LAN
A serial interface is redirected by LAN using the RMCP+ protocol.
