Dell Mellanox CX422A ConnectX-4 Dual Port 25GB SFP rNDC

This Dell Mellanox CX422A ConnectX-4 rNDC is a rear network daughter card that adds two 25GbE SFP28 ports to Dell PowerEdge servers. It installs in the dedicated rNDC slot in systems such as the PowerEdge R640, R740, R740xd, R840, R940, and R940xa, leaving standard PCIe slots available for other adapters. Use it with 25Gb SFP28 transceivers or direct-attach cables and matching switch ports; compatibility depends on the server’s rNDC slot support, Dell firmware and driver support, and the intended optical or DAC cabling.
