LEDs
•
LED1 (red):
Out-of-Service LED
•
LED2 (red/green):
Health LED
•
HS LED (blue):
The hot swap indicator provides basic feed-
back to the user on the hot swap state of the
module. The HS LED states are off, short
blink, long blink, and on.

Watchdog Timer
•
Software-configurable, two-stage Watchdog with programmable timeout
ranging from 125 ms to 4096 s in 16 steps
•
Serves for generating IRQ or hardware reset
System Timer
•
The Intel® QM57 chipset contains three 8254-style counters which have
fixed uses
•
In addition to the three 8254-style counters, the Intel® QM57 chipset in-
cludes eight 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.
IPMI
Module Management
Controller
•
NXP® LPC2368 ARM7 microcontroller with redundant 512 kB 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 Intelligent Platform Management Bus
(IPMB-L) and one host Keyboard Controller Style interface (KCS).
Hot Swap
The AM5020 has full hot swap capability.
Thermal Management
CPU and board overtemperature protection is provided by:
•
Temperature sensors integrated in Intel® Core™ i7 processor:
•
Two temperature sensors for monitoring the processor cores
•
One temperature sensor for monitoring the graphics controller and
the memory controller
•
One temperature sensor integrated in the Intel® QM57 chipset for mon-
itoring the chipset
•
One onboard air temperature sensor for monitoring the board tempera-
ture
•
Specially designed heat sinks
