Hi,

We have a host with a ConnectX-3 adapter connected to a SX6036 InfiniBand Switch (https://www.mellanox.com/related-docs/prod_ib_switch_systems/PB_SX6036.pdf) using FDR10 cable (https://store.mellanox.com/products/nvidia-mc2206310-030-active-optical-cable-infiniband-qdr-fdr10-40gb-s-qsfp-30m.html).

We would like to know if the ConnectX-3 FDR10 adapter can be replaced with a ConnectX-5 EDR adapter using the same cable.

Thank you.
