Figure 45. Installing the air shroud

Next steps

1. Follow the procedure listed in 

After working inside your system

 on page 28.

Cooling fans

Cooling fan specifications

The cooling fans are integrated into the system to dissipate the heat generated by the functioning of the system. These fans
provide cooling for the processors, expansion cards, and memory modules.

Your system supports a total of eight fans, including six hot-swappable fans and two external fans. Two hot-swappable fans
are mounted in rear side of the air shroud. The other four hot-swappable (middle) fans are mounted in the fan assembly that is
located in the chassis between the hard drive bay and the processors. The two external fans are mounted on the outside of the
chassis for GPU configurations. There are two additional fans integrated in the power supplies to cool the power supplies and
provide additional cooling for the whole system.

The below listed configurations, features, and the PCIe expansion cards are supported only with the four hot-swappable
(middle) fans installed:

●

Fan redundancy

●

Fresh air condition

●

NVMe/PCIe SSD

●

3.5 inch x 18 hard drives chassis

●

Mellanox CX4 DP 100 Gb QSFP NIC (0272F)

●

Mellanox CX4 DP 100 Gb NIC (068F2)

●

Mellanox CX4 SP 100 Gb NIC (6W1HY)

●

Mellanox DP 40 Gb QSFP NIC (C8Y42)

●

Intel QP 10 Gb Base-T NIC (K5V44)

●

Solarflare Sunspot DP 10Gb NIC (NPHCM)

●

Solarflare Nova DP 10Gb NIC (WY7T5)

●

Qlogic DP 10Gb V1 NIC (VCXN5)

Listed below are the restrictions for fan redundancy:
