14 IPMI Functions List

The ATCA-S201 module supports the intelligent platform management interface (IPMI) version 1.5. This system is used to collect status information from on on-board sensors as well as sensors installed on AMC or RTM modules. Collected information items include:

∙Hot swap communication with the shelf manager

∙Inlet air temperatures

∙Voltage monitoring

∙Electronic Keying as described in the AMC.0 specification

∙FRU information

∙Drives blue LED indicators for hot swap, OOS (out of service)

∙Drives green LED for module “OK”

The RTM-ATCA-SXXX module includes an MMC device for reporting status information to the ATCA blade. This MMC utilizes an Intelligent Platform Management Interface (IPMI) which will communicate with the ATCA. This MMC controls and monitors the following:

∙Hot Swap communication with the shelf manager

∙Inlet air temperatures

∙Voltage monitoring

∙Electronic Keying as described in the AMC.0 specification

∙FRU information

∙Drives “blue” LED indicators for Hot Swap. OOS (out of service),

∙Drives “green LED for module “OK”

14.1IPMI and Management Controller (IPMC)

The design features an IPMI controller consisting of a 16-bit microcontroller, flash and SRAM. The microcontroller uses I2C interface to communicate the shelf management controller (ShMC), sensors, and MMC devices on AMC modules and the RTM if installed.

∙Support hot-swap operation as defined for AMC modules in PICMG AMC.0 specification “Fail-safe flash update” - if interrupted at anytime, the MMC firmware is still able to respond and re-flash.

14.2Sensor data records

The MMC monitors the status of the module and provides this data so it can be read by the shelf manager. Below are the SDRs that the ATCA-S201 and the RTM-ATCA- SXXX modules create.
