D.14 ASM Operation
A discussion of how ASM features are used by the Ultra AXi can be found in
Section 3.4 “Advanced System Monitoring (ASM)” on page 3-9.
Supported
env-monitor
values
1.
enabled-with-fans:
If set, OBP monitors and reacts as follows:
■
If the CPU thermistor temperature is above the warning temperature
threshold, a warning is issued.
■
If the CPU thermistor reading is above the shutdown temperature threshold,
the system will shutdown.
■
If either of the voltages are out of the acceptable range, OBP issues a warning
for out of range values.
■
The optional fans are monitored and a warning is issued if the fans are not
present or if they fail.
2.
enabled:
same as
enabled-with-fans
without optional fan checking.
Caution – Because the CPU fan is required for CPU modules with straight fin
heatsinks (e.g., 360 MHz, part number 501-5148-xx; 440 MHz, part number 501-5149-
xx), only use
enabled-with-fans
.
3.
disabled:
Does not monitor any ASM features at OBP level. It creates the
device tree node and properties for OS, but OS considers the monitoring disabled.
4.
disabled*:
This value turns off OBP monitoring and does not create the device
tree node. (The
*
is part of the setting, not a reference to a footnote).
