Watchdog Timer
•
Software-configurable, two-stage Watchdog with programmable timeout
ranging from 125 ms to 256 s in 12 steps
•
Serves for generating IRQ or hardware reset
System Timer
•
The Intel® 3100 chipset contains three 8254-style counters which have
fixed uses
•
In addition to the three 8254-style counters, the Intel® 3100 chipset in-
cludes three individual high-precision event timers that may be used by
the operating system. They are implemented as a single counter each
with its own comparator and value register.
•
Hardware delay timer for short reliable delay times
IPMI
Module Management
Controller
•
Renesas H8 microcontroller with 40 kB RAM and redundant 512 kB
Firmware Flash with 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 two host Key-
board Controller Style (KCS) interfaces
Hot Swap
The AM4011 has full hot swap capability.
Thermal Management
CPU and board overtemperature protection is provided by:
•
Four temperature sensors for monitoring the board temperature
•
Six processor sensors
•
One chipset sensor
•
Specially designed heat sink
Option
USB 2.0 NAND Flash
Up to 8 GB USB 2.0 NAND Flash memory can be added to the AM4011 using
an optionally available USB 2.0 NAND Flash module.
