the air flow indicator arrow is completely visible as shown in callout 1,
air flow indicator arrow points in the direction the fan unit flows air through the fan module.
In the I/O port to power supply module (default) air flow configuration, the fan unit is visible (as
shown in Figure
When the fan unit is reversed, a metal plate covers the fan unit (as shown in
the fan module air flow:
1. Hold the module in your hand.
2. Apply pressure to the edges of the fan units closer to the fan module connector to rotate the
