Refer to the exhibit. A customer recently replaced all the dual-port network cards in mezzanine A with quad-port network cards across all 16 PowerEdge MX740c sleds in the two-chassis configuration…

Explanation

Option B is correct because upgrading from dual-port to quad-port mezzanine cards doubles the available fabric paths, but the physical fabric interconnect infrastructure must be expanded to support them. The MX7116n Fabric Expander Module requires an additional 200G cable to provide the uplink path for the newly active ports (3 and 4) on the quad-port NICs - without it, those ports have no fabric route even if iDRAC detects the hardware. Option A (virtual reseat) is a management-layer reset that cannot create missing physical cable paths. Option C (reboot switches) is irrelevant because the issue is absent cabling, not a switch state problem - the hardware is already visible in iDRAC. Option D (reseat switches) addresses loose physical seating, not a missing interconnect between chassis fabric modules.

Memory tip: "More ports, more pipes." Going from dual to quad NICs doubles port density, so the fabric expander needs a new cable to carry the added traffic - iDRAC sees the card, but the signal has nowhere to go without the extra 200G link.
