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.
Interpreting fan assembly LEDs
Refer to the following illustration and table to interpret the LED patterns on fan assemblies. The LED patterns may temporarily change
during POST and other diagnostic tests. The Brocade X6-4 Director has two fan assemblies.
