10 Gbps dual SFP+ card

The AddOn E10G42BFSR-AO is a PCIe x8 network interface card built around the Intel 82599 chipset. It ships with two 10GBase-SR SFP+ transceivers installed in the open ports. The card targets servers and workstations that need fibre uplinks at ten gigabits per second. Compatibility covers Windows Server 2012 and Linux kernel 2.6.30 or greater.

Upgrade from single-port or copper 10G

This card replaces a single-port 10 Gbps adapter or a copper-based 10GBASE-T NIC when fibre cabling is already in place. The jump is worth it when a second physical link is needed for redundancy, link aggregation or separate traffic streams. Two SR transceivers are included, so no separate optics purchase is required for short-reach multimode runs.

Suits fibre-ready racks, not copper-only builds

The product suits administrators deploying short-reach multimode fibre in racks that already have LC patching. It does not suit environments that only have Cat6a or Cat7 cabling and no plan to add fibre. Buyers who need longer reach, different wavelengths or a single-port layout should look at other models.

Questions about this item

Will the PCIe x8 card fit in a standard full-height expansion slot?

Yes, it installs in any PCIe x8 or wider slot and uses a full-height bracket.

What driver step is often missed when installing the Intel 82599-based card on Linux?

Load the ixgbe module included in kernel 2.6.30 or newer; the card will not appear until the module is active.

When should the two included 10GBase-SR transceivers be replaced?

Replace them if link lights fail, error counters rise, or after a firmware update that changes supported optics.
