Module Management
Controller
•
NXP® ARM7 microcontroller with a 4MB external firmware flash and
automatic roll-back strategy
•
The MMC carries out IPMI commands such as monitoring several on-
board temperature conditions, board voltages and the power supply sta-
tus, and managing hot swap operations.
•
The MMC is accessible via a local IPMB (IPMB-L) and one host Key-
board Controller Style Interface (KCS).
•
One MMC system EEPROM for FRU data and firmware private data
Hot Swap
The AM4120 has full hot swap capability.
Thermal Management
CPU and board overtemperature protection is provided by:
•
One onboard temperature sensor for monitoring the board temperature
•
Specially designed heat sink
