Note

When a part with active optical cable (AOC) is installed and the rate of the part is greater than 25 GB, the ambient temperature must be limited to 30°C or lower.
When the following parts are installed, the ambient temperature must be limited to 35°C or lower.
- PCIe network interface cards (NICs) at a rate greater than or equal to 100 GB
- Parts with AOC and at a rate of 25 GB
When standard fans are used, the max. supported ambient temperature is 30°C; when performance fans are used, the max. supported ambient temperature is 35°C.

This section provides thermal information for storage configurations with DWCM.

Front bays	Middle bays	Rear bays	Max. Temp.	Processor	Heat sink	Air baffle	Fan type	Support ≥ 64 GB DIMM

Note

When standard fans are used, the max. supported ambient temperature is 30°C; when performance fans are used, the max. supported ambient temperature is 35°C.
The ambient temperature is limited to 30°C when the following NVMe drives are installed in middle or rear drive bays:
- Gen5 7.68 TB or larger capacity
- Gen4 P5336 15.36T/30.72T/61.44T NVMe

This section provides thermal information for storage configurations without DWCM.
