Air Flow

These switches can come with two air flow patterns. The two patterns are:
• Connector side inlet to power side outlet
• Power side inlet to connector side outlet
The air flow is specified in the product model number. See "Mellanox Part Numbering Legend"
on page 10.On the PS unit and fan modules the air flow direction can be seen on the power side
panel. All components need to have the same air flow. A mismatch in the air flow will affect the
heat dissipation.
Figure 13 shows a mismatch in component airflow.
