Questions about this item

How much power does the 100G CX566A draw under sustained load?

The supplier data does not publish a power-draw figure for the CX566A, so exact wattage under load cannot be stated.

Which server slots accept the OCP 3.0 form factor of this card?

The card is built for the OCP 3.0 slot used in Dell PowerEdge R750, R7525 and R650 servers.

Can the CX566A share a backplane with older 25G or 10G NICs in the same chassis?

Yes, the OCP 3.0 interface is electrically backward-compatible so the CX566A can coexist with lower-speed adapters in supported PowerEdge systems.
