NOT dual-port. Single QSFP56 cage only.
NOT a standard NVIDIA retail card. Dell OEM firmware — verify and, where licensing permits, reflash before deploying in non-Dell hosts.
NOT supplied with cables or transceivers. Order matching QSFP56 HDR DAC, AOC, or optical transceivers separately.

Frequently Asked Questions (FAQ)
Q. What is the Dell 0CY7GD?
Dell OEM Mellanox ConnectX-6 VPI: single QSFP56 port at full HDR 200Gb/s — InfiniBand HDR or 200GbE Ethernet. Dell PowerEdge qualified.
Q. Is 0CY7GD HDR 200G capable?
Yes — full HDR 200Gb/s per port via InfiniBand HDR or 200GbE Ethernet (VPI dual-protocol).
Q. How does 0CY7GD differ from 07TKND?
0CY7GD runs full HDR 200Gb/s. 07TKND runs HDR100 at 100Gb/s. Both are single-port ConnectX-6 VPI Dell OEM adapters.
Q. Can 0CY7GD be used in non-Dell servers?
Possibly — Dell OEM firmware may restrict operation in third-party hosts. Reflash to NVIDIA generic firmware where licensing permits, and verify before deploying.
