1.4 Module Management Controller Hardware
On the AM5030 processor AMC module, the MMC is implemented using the NXP LPC2368
microcontroller with 512 kB of internal flash and 56 kB of RAM.
An external 64 kB serial EEPROM chip is used for firmware private data and for FRU Inventory
storage. An additional external 2 MB serial SPI-Flash is used for redundant firmware image
storage.
The Module Management Controller implements one local Keyboard Style Interface (KCS) with
interrupt support for communication with system side management software and the uEFI BI-
OS. The IPMB-L bus is used for interconnection with the IPMC.
IPMI over LAN (IOL) as well as Serial Over LAN (SOL) is supported on all four Ethernet chan-
nels of the module. SOL is only available on one Ethernet channel at a time.
The Module Management Controller provides access to various board sensors which permit
the monitoring of:
• System power voltages: +12V (PWR), +5V, +3.3V, +3.3V (MP)
• Temperatures: inlet and outlet near AMC edge-connectors
• Power Good, LAN links, IPMB link, board reset, post code, boot error, CPU States (pro-
cessor hot, thermal trip, …), IPMB-L state, Health error, IPMI watchdog etc.
2. MMC Firmware
2.1 Key Features
The following are key features of the AM5030 MMC Firmware:
• Compliant with the related IPMI and PICMG® specifications
• Firmware designed and specially made for AdvancedMC environments (ATCA, µTCA)
• Supports one KCS interface with interrupt support
• Supports the local IPMB (IPMB-L) interface
• Out-of-Band management and monitoring using IPMB-L interface permits access to
sensors regardless of module CPU state
• Sensor thresholds fully configurable
• Sensor names prefixed with AMC module Bay ID (A1…4, B1…4)
• Usable in µTCA slots 1…12. Sensor names for slots 9…12 are prefixed with C1…C4
• Complete IPMI watchdog functionality
• Complete FRU functionality
• Firmware can be updated in the field
• Two firmware banks implemented, firmware bank management is done by the open tool
“ipmitool” (functions “hpm” or “fwum”)
• Down loading new firmware image does not break currently running firmware activities
• Manual and automatic firmware image roll-back in case of upgrade failure
