This chapter describes the Module Management Controller (MMC) and Intelligent Platform Management Interface (IPMI).
This chapter contains the following topics:
A.1 MMC and IPMI Functions
The Netra CP32x0 ARTM-10G module includes a Module Management Controller (MMC) device for reporting status information to the ATCA blade. This MMC uses an Intelligent Platform Management Interface (IPMI), which communicates with the AdvancedTCA.
The MMC controls and monitors the following:
- Hotswap communication with the shelf manager
- Inlet air temperature
- Voltage monitoring
- Electronic keying (e-Keying), as described in the AMC.0 specification
- FRU information
- BLUE LED indicators for hotswap
- OOS (out of service) LED indicator
- GREEN LED indicators for “ok”
From the management perspective, the MMC implementation conforms to the ARTM port commands specified in the AdvancedTCA specification. An ATCA board communicates to the ARTM using site ID 15, and thus an IPMBL address of 0x8E.
Additional features of the MMC implementation include:
- An I2C connection provides communication path between the MMC and the temperature sensor. Also, the I2C serial bus routes to the SFP+ modules.
- Supports hot-swap operation as defined for AMC modules in PICMG AMC.0 specification.
- Provides “fail-safe flash update;” if interrupted at anytime, the MMC firmware is able to respond and reflash.
- Provides “I2C hang recovery;” the MMC is able to detect and recover from an I2C bus hang.
A.2 Sensor Data Records
The MMC monitors the status of the ARTM and provides data so it can be read by the shelf manager. The sensor data records (SDRs) that the Netra CP32x0 ARTM-10G monitors are described in TABLE A-1.
