Dual 25Gb SFP28 rNDC for Dell PowerEdge

This dual-port 25Gb SFP28 rNDC is built for Dell PowerEdge servers needing high-throughput network connectivity. It suits administrators upgrading R640, R740, R740XD, R7425, R840, R940 or R940XA platforms. The card delivers two 25Gb lanes through a single mezzanine slot.

Tested components with updated firmware

Each unit ships with components tested and firmware updated before dispatch. That preparation reduces first-boot driver mismatches and cuts the time spent applying vendor patches. No extra cables, transceivers or licences are included in the package.

Mezzanine installation in supported chassis

Installation follows the standard rNDC mezzanine procedure for the listed PowerEdge models. The card seats directly into the designated rNDC bay without adapters. Common issues arise when the server BIOS or iDRAC firmware is older than the minimum required for QL41262 support, or when SFP28 transceivers are not qualified for the target switch.

Questions about this item

Will the SFP28 transceivers need replacement as speeds increase beyond 25 Gb?

The adapter is built for 25 Gb links; faster transceivers would require a different controller.

What throughput ceiling appears first when the dual 25 Gb ports run flat out?

Each SFP28 port tops out at 25 Gb, so the port speed is the first hard limit under sustained load.

How much extra heat does the QL41262 add when running continuously in a PowerEdge R740?

The card draws power only for two 25 Gb SFP28 links; the server's existing cooling handles the incremental load.
