Intel X540 Dual Port 10GBASE-T NIC
The EDGEOPTIC 10G-NIC-X540-2T pairs the Intel X540 Ethernet controller with two RJ45 ports for 10GBASE-T copper connectivity on a PCI Express 2.1 x8 card. Each port runs at 10GbE, 1GbE or 100Mb, with SR-IOV, VMDq and VLAN support for virtualized hosts, plus iSCSI, FCoE and NFS storage over Ethernet, PXE boot, jumbo frames and Wake on LAN. A low profile bracket ships attached and a standard bracket is included, so the card fits both low profile and standard height chassis.

Intel X540 Dual Port 10GBASE-T RJ-45 Network Interface Card Description
The EdgeOptic 10G-NIC-X540-2T is a dual port 10GBASE-T network interface card built on the Intel X540 Ethernet controller. Each RJ45 port runs 10GbE, 1GbE or 100Mb over a PCI Express 2.1 x8 host interface at 5GT/s or 2.5GT/s.
Copper reach extends to 55 meters on CAT6 cabling and 100 meters on CAT6A. Link and activity LEDs show green at 10Gbps and yellow at 1Gbps.
The controller supports SR-IOV with 64 virtual functions, VMDq with 64 pools, and VLAN tagging for virtualized environments. Storage over Ethernet runs through iSCSI, FCoE and NFS, including iSCSI boot, with jumbo frames, PXE boot and Wake on LAN support.
Standards support covers IEEE 802.3an 10GBASE-T, 802.3x flow control, 802.3ad link aggregation, 802.1Q VLAN, 802.1Qaz Enhanced Transmission Selection and 802.1Qbb Priority Flow Control.
The card measures 146 by 69mm with a low profile bracket attached and a standard bracket. Operating temperature is rated 0 to 55C, storage minus 40 to 70C, with 200 LFM airflow and 5 to 90 percent RH non condensing. Power draw runs 6.6W at 100Mbps, 9.5W at 1Gbps, up to 17.4W at 10Gbps on 3.3V and 12V rails.
Management options include PXE Boot, iSCSI Boot, SNMP, RMON and the Intel PROSet Utility. Supported operating systems span Windows Server 2008 through 2019, Windows 7 through 10, RHEL, SLES, Ubuntu, VMware ESXi and FreeBSD, with CE, FCC and RoHS compliance.

Frequently Asked Questions
Does the 10G-NIC-X540-2T fit in a PCIe x16 slot?
Yes. The card uses a PCI Express 2.1 x8 edge connector, and a PCIe x8 card is mechanically and electrically compatible with a PCIe x16 slot. The slot negotiates down to the card's x8 link width and the card operates normally.
What is the difference between this X540 RJ45 card and an SFP+ 10G card such as the Intel X520-DA2?
The 10G-NIC-X540-2T is built on the Intel X540 controller and supports 10GBASE-T copper over RJ45 only. There is no SFP+ variant of the X540 controller. The X520-DA2 uses a separate Intel controller built for SFP+ fiber or direct attach copper connections. Choose the X540-2T for RJ45 copper cabling and the X520 family for SFP+ transceivers or DAC cables.
Does the 10G-NIC-X540-2T support 2.5GbE or 5GbE?
No. Each port on the X540 controller operates at 10GbE, 1GbE or 100Mb only. The intermediate 2.5GBASE-T and 5GBASE-T rates defined in IEEE 802.3bz are not part of the X540 controller's supported speed set.
Is the Intel X540 controller series still in production?
Intel has issued PCN 118137-01 designating the X540 controller series as end of life. EdgeOptic's 10G-NIC-X540-2T remains available on a made to order basis per its current listing; check the product page for current lead time before planning a deployment around this card.
