System configuration Cooling fan Foam requirement
8 x 2.5-inch NVMe High performance (silver grade) fan Not required
16 x 2.5-inch SAS/SATA High performance (silver grade) fan Not required
16 x 2.5-inch SAS/SATA + 8 NVMe High-performance (gold grade) fan Required
16 x 2.5-inch NVMe High-performance (gold grade) fan Required
8 x 3.5-inch SAS/SATA High performance (silver grade) fan Required
NOTE: 12 x 3.5-inch and 24 x 2.5-inch NVMe system do not support GPU/FPGA card.
2. Remove the heat sink and install the required L-type heat sink.
NOTE: All GPU/FPGA cards require L-type heat sink and GPU shroud, irrespective of the length.
3. Remove the air shroud and install the GPU air shroud.
4. Remove the GPU air shroud top cover.
NOTE: The GPU air shroud top cover is part of the GPU air shroud.
5. Install the GPU.
Refer to the riser and GPU slot configuration table to know about the slots for the GPU installation.
