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.
NOTE
If airflow direction for a power supply assembly does not match the chassis airflow direction as stored on WWN cards, the
power supply will have a "fault" status. However, LED operation for the power supply will not indicate a fault. If airflow direction
for a fan assembly does not match the chassis airflow direction, the fan LED will indicate a fault condition.
Power supply and fan assemblies are labeled with a green "E" or orange "I" airflow symbol. All fans and power supplies in a chassis must
have the same label affixed to guarantee airflow direction is consistent.
