Non operation temperature: -40? ~ 70? Non operation humidity: 20% ~ 90% ( Non condensing) Note * M.2 socket (PCIe mode) shares the bandwidth with Location-4 PCIe x16 slot (Gen3 x4 link). ** An external fan module is required with NVIDIA Tesla cards, and acoustic level will be high. *** Suggest to use Intel Xeon W-3200 processors which support PCIe slots with full CPU links(64 lanes). Intel Xeon Scalable processors are supported, but there may be some limitations of CPU links(48 lanes).
