The Alveo X3522 NICs support airflow in either direction:
- Normal flow, where airflow is out from the I/O bracket.
- Reverse flow, where airflow is into the I/O bracket.
Figure 1. Airflow Direction for X3522 NICs
The following table shows requirements for
Alveo
X3522 NICs that are dependent on airflow
direction.
Specification | Requirements |
---|---|
DSFP case temperature for airflow entering PCIe bracket | DSFP(≤ 2.5W) case should be rated 70°C |
DSFP case temperature for airflow exiting PCIe bracket | DSFP (≤ 2.5W) case should be rated 85°C |
Airflow entering PCIe bracket area | 66.87 mm x 13.18 mm |
Airflow exiting PCIe bracket area | 56.51 mm x 20.33 mm |
