Description (partial)

The chassis FAN speeds will spin at 100% because the chassis/IOM cannot obtain DIMM temperature readings from a blade. When in this state, the blade can no longer obtain DIMM temperature sensors.

An invalid I2C transaction occurred on the DIMM I2C bus. These transactions often come from software running on the x86 host.
