Smart Embedded Management Agent (SEMA)
The onboard microcontroller (BMC) implements power sequencing and Smart Embedded Management Agent (SEMA) functionality. The
microcontroller communicates via the System Management Bus with the CPU/chipset. The following functions are implemented
Total operating hours counter counts the number of hours the module has been run in minutes.
•
On-time minutes counter counts the seconds since last system start.
•
Temperature monitoring of CPU and board temperature minimum and maximum temperature values of CPU and board are stored in
flash.
•
Power cycles counter
•
Boot counter counts the number of boot attempts.
•
Watchdog Timer (Type-II) Set, Reset, Disable Watchdog Timer. Features auto-reload at power-up.
•
System Restart Cause Power loss, BIOS Fail, Watchdog, Internal Reset, External Reset
•
Fail-safe BIOS support In case of a boot failure, hardware signals tells external logic to boot from fail-safe BIOS.
•
Flash area 1kB Flash area for customer data
•
128 Bytes Protected Flash area Keys, IDs, etc. can be stored in a write- and clear-protectable region.
•
Board Identify Vendor, Board, Serial number, Production Date
•
Main-current & voltage monitors drawn current and main voltages
