Managing the AMC

This chapter describes the AMC management software.

The Sun Netra CP3000 AMC.1-HDD SAS disk includes an IPMI-based Module Management Controller (MMC) 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.1-HDD SAS disk and management controllers on the carrier board and system level. Board voltages, temperature, and hot-swap handle status are all monitored by the MMC.

This chapter contains the following topics:

Section 3.1, Monitoring and Control Functions

Section 3.2, IPMI Controller

Section 3.3, FRU Information

Section 3.4, Sensors

Section 3.5, Firmware and Software Upgrades

3.1 Monitoring and Control Functions

The MMC is responsible for communicating module status information to the carrier board, and also has 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 that the interface is compatible). The MMC has the ability to reset the PHY through the IPMI FRU Control command.

3.2 IPMI Controller

The IPMI controller consists of a 16-bit microcontroller, flash, and SRAM. The microcontroller uses I2C interface (IPMB-L) to collect data from various sensors located on the AMC. The host ATCA blade server might read data collected by the IPMI controller, and transmit it to the shelf management controller (ShMC) through the IPMB-0.

The IPMB is routed through the AMC connector to the host carrier blade and backplane. The IPMB allows the AMC MMC to be discovered by and communicate with the carrier blade and system-level management. It is always active.

The MMC communicates with the carrier controller through the local IPMB-L bus of the carrier and responds to all mandatory commands for AMC MMC (as defined in the AMC Specification), as well as some optional commands.

3.3 FRU Information

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 onboard the AMC.1-HDD SAS disk complies with the PICMG 2.9 specification.

The AMC.1-HDD SAS disk includes the standard FRU data records per the IPMI Platform Management FRU Information Storage Definition, Board Info Area. The AMC.1-HDD SAS disk includes additional FRU records as defined in the PICMG 2.9 specification.

3.4 Sensors

The AMC.1-HDD SAS disk module management is connected to sensors monitoring key board voltages and temperatures. Data records from the following sensors are accessible using IPMI commands:

Hot-swap

+12V payload power

+3.3V management power

Board and inlet temperature

+1.2V onboard voltage (generated from payload)

+3.3V onboard voltage (generated from payload)

Note - The sensor index number is dynamically created by the shelf manager and might not always start at index zero (0).
