Assertion –A fan was inserted. This
event may also get logged when the
BMC initializes when AC is applied. Informational only
Deassert – A fan was removed, or
was not present at the expected
location when the BMC initialized
These events only get generated in systems with hot-swappable fans, and normally
only when a fan is physically inserted or removed. If fans were not physically removed:
1. Use the Quick Start Guide to check if the right fan headers were used.
2. Swap the fans round to see if the problem stays with the location, or follows
the fan.
3. Replace fan or fan wiring/housing depending on the outcome of step 2.
4. Ensure the latest FRUSDR update has been run and the correct chassis was
detected or selected.
