installation priority
PCIe adapters
Must be installed in slot 1
• SFF HBA/RAID adapter
• ThinkSystem x16 Gen 4.0 Re-timer adapter (for 4x NVMe)
Must be installed in slot 2
(configured as a full-height
slot)
• ThinkSystem NVIDIA Quadro P2200 5GB PCIe Active GPU
• ThinkSystem Broadcom 57454 10/25GbE SFP28 4-port PCIe Ethernet Adapter
Must be installed in slot 3
ThinkSystem Mellanox HDR/200GbE 2x PCIe Aux Kit
Note: ThinkSystem Mellanox HDR/200GbE 2x PCIe Aux Kit must be used together
with Mellanox ConnectX-6 HDR IB/200GbE Single Port x16 PCIe Adapter and
functions as the auxiliary adapter. Two CPUs are required if both adapters are used,
with the primary adapter installed in slot 1 or slot 2 while the auxiliary adapter installed
in slot 3.
Slot 1 > Slot 3 > Slot 2
• ThinkSystem NVIDIA Tesla T4 16GB PCIe Passive GPU
• NVIDIA Tesla T4 16GB Base Card (for China only)
• NVIDIA Quadro P620 GPU
• Mellanox ConnectX-6 HDR100 IB/100GbE VPI 1-port x16 PCIe 3.0 HCA
• Mellanox ConnectX-6 HDR100 IB/100GbE VPI 2-port x16 PCIe 3.0 HCA
• Mellanox ConnectX-6 Dx 100GbE QSFP56 2-port PCIe Ethernet Adapter
Slot 2 > Slot 3 A COM port upgrade kit needs to be installed in slot 2 or 3 as a normal PCIe adapter.
In this case, a riser and bracket are needed.
Slot 1 > Slot 2 > Slot 3 Other PCIe adapters not mentioned above
Notes: For Mellanox ConnectX-6 HDR IB/200GbE Single Port x16 PCIe Adapter, refer
to the following slot priority depending on the quantity of adapters to be installed:
• Two adapters: slot 1, slot 3 or slot 2, slot 3
• Three adapters: slot 1, slot 2, slot 3
