2.2 Air Flow
Mellanox systems are offered with two air flow patterns:
• Connector (front) side inlet to power side outlet - marked with red power supplies/fans
FRUs’ handles, as shown in Figure 4.
• Power (rear) side inlet to connector side outlet - marked with blue power supplies/fans
FRUs’ handles, as shown in Figure 5.

All servers and systems in the same rack should be planned with the same airflow
direction.
All FRU components need to have the same air flow direction. A mismatch in the air
flow will affect the heat dissipation.
Table 6 provides an air flow color legend and respective OPN designations.
