Lenovo ThinkSystem Intel E810-DA4 10/25GbE SFP28 4-Port OCP Ethernet Adapter

Four SFP28 ports on one OCP 3.0 module are the feature of the Lenovo ThinkSystem Intel E810-DA4 10/25GbE SFP28 4-Port OCP Ethernet Adapter, part number 4XC7A80269. The ports are rated at 10/25GbE and managed by an Intel E810 controller.

With four ports, a single module can carry production, storage, backup and management links, or provide grouped connections for resilience. Because it occupies the server's OCP slot, standard PCIe slots stay free for other cards. Confirm your server has an OCP 3.0 slot, since a PCIe version would be a separate part.

The DA4 in the name marks four ports; the DA2 module is the two-port equivalent. Read that part of the name when replacing a card to keep your cable plan intact.

SFP28 cages accept SFP28 optics or direct attach cables bought separately. Dual-speed ports allow a mixed 10GbE and 25GbE switch environment.

Offers are new and refurbished, each with a choice of 1 year or 3 years of warranty. No used unit is listed. Include your quantity and server model in the request.
