Notes: a.The ConnectX-6 adapters 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 Mellanox InfiniBand product.
b.Typical power for ATIS traffic load.
c. For both operational and non-operational states.
d. For engineering samples - add 250LFM
