Dual Port 25/10Gbe Adapter

The QLogic QL41212HLCU-CK provides two SFP28 and SFP+ ports for 25 and 10 Gigabit Ethernet connectivity over PCIe. It supports L2, RoCE and iWARP protocols for low-latency data transfer. This adapter suits servers and workstations that need high-speed network links without proprietary interconnects. It is not for systems lacking a compatible PCIe slot or SFP transceiver budget.

Standard PCIe Installation

Installation follows the usual PCIe add-in card procedure: power down, insert into an available slot, secure the bracket and attach supported transceivers. Driver support depends on the host operating system and kernel version. Common issues arise when switch ports are not configured for the negotiated speed or when DAC cables exceed the supported reach. Buyers without switch management access may struggle to complete the link.

Questions about this item

How do I verify the QL41212HLCU-CK adapter is operating at 25 GbE after installation?

Check the link status LEDs on the bracket; a solid green indication confirms a 25 GbE link, while amber shows a 10 GbE connection.

Does the QL41212HLCU-CK include SFP28 or SFP+ transceivers, or must they be purchased separately?

The adapter ships without transceivers; you must buy compatible SFP28 modules for 25 GbE or SFP+ modules for 10 GbE links.
