Managing the AMC |
This chapter describes the AMC management software.
The Sun Netra CP3240 AMC.2-OP includes an IPMI-based MMC (Module Management Controller) that meets all requirements set out in the PICMG AMC.0 specification. The MMC allows detection of the module by the carrier board and manages communication between the AMC.2-OP and management controllers on the carrier board and system level. Board voltages, temperature, and hot-swap handle status are all monitored by the MMC as well.
This chapter contains the following topics:
The MMC is responsible for communicating module status information to the carrier board, but it also carries out some control at the module level. The 10GbE local PHY is held in reset until the AMC Carrier IPMI uses e-Keying to turn on the interface (to ensure the interface is compatible). The MMC has the ability to reset the PHY via IPMI FRU Control command.
The IPMB is an I2C interface routed through the AMC connector to the host carrier board and backplane. The IPMB allows the AMC MMC to be discovered by and communicate with the carrier board and system level management. It is always active.
Board information such as serial number, date of manufacture, OEM name, part number, and so on is retrievable from the FRU EEPROM integrated into the MMC. FRU information stored on board the AMC.2-OP complies with the AMC.0 specification.
The AMC.2-OP module management is connected to sensors monitoring key board voltages and temperatures. Data records from the following sensors are accessible using IPMI commands:
* All AMC modules are required to have at least two temperature sensors.
