2.2 Air Flow
Mellanox systems are offered with two air flow patterns:
• Connector (front) side inlet to power side outlet - marked with red labels on the power
supply side as shown in Figure 2.
• Power (rear) side inlet to connector side outlet - marked with blue labels on the power
supply side as shown in Figure 3.
Table 6 provides an air flow label color legend and respective OPN designations,
All servers and systems in the same rack should be planned with the same air-
flow direction.
All FRU components need to have the same air flow direction. A mismatch in
the air flow will affect the heat dissipation.
