Suits PowerEdge Rack Servers Listed

The adapter is validated for specific Dell PowerEdge models including R640, R650, R6525, R660, R6615, R6625, R740, R740XD, R740XD2, R750, R750xa, R7515, R7525, R760, R760xa, R760XD2, R7615, R7625, R840, R860, R940, R940XA, R960, XE8545, XR5610, XR7620, XR8610T, and XR8620T. Builders using other server platforms or needing a low-profile bracket should look elsewhere.

QSFP56 Dual-Port Interface Decides Fit

The card uses a dual QSFP56 interface running at 100GbE per port. Confirm your chassis has a full-height PCIe slot and QSFP56 cabling or transceivers available; without that physical and electrical match the adapter cannot be installed.
