Fan Sensors
The server module contains six fan modules labeled fm[0-5]. Each module contains
two fans.
fm[0..5].f[0..1].speed
All top-accessable fan speed sensors are configured to generate the same events and
all faults are handled in the same way. They are not monitored when the host is
powered off.
fm[0..5].fail
This is a GPIO signal indicating fan module failure status.
CPU [0..1] and DIMM Sensors
There are two CPUs per server module.
