B4240L Liquid-Cooled Platform Specifications

Notes: ^(a) The BlueField-4 DPU supplement the IBTA auto-negotiation specification to get better bit error rates and longer cable reaches. This supplemental feature only initiates when connected to another NVIDIA InfiniBand product. ^(b) The non-operational storage temperature specifications apply to the product without its package.
