Fan and power supply airflow
All fans and power supply FRUs installed in this device must have either NPI
(nonport-side intake) or NPE (nonport-side exhaust) airflow. You must order a
replacement FRU with the same part number (P/N) as the FRU being replaced to
provide the same airflow. The manufacturing P/N, located on the top of the FRU,
contains either NPI or NPE. If a mismatched power source or fan assembly is
installed by mistake, a RASlog message occurs indicating that a mismatch in fan or
power supply airflow has occurred and the FRU is faulted.
