10Gbps Single-Port RJ45 Adapter

The Intel X540T1BLK is a PCIe 2.1 x8 network card that adds one 10GBASE-T RJ45 port to a server or workstation. It supports 802.3, 802.1Q, 802.1p and 802.3ad standards for VLAN tagging, priority queuing and link aggregation. The controller integrates Intel VT-c, Data Direct I/O and intelligent offloads for iSCSI, FCoE and NFS traffic.

Suited for 10GBASE-T Infrastructure

This card targets administrators upgrading existing Cat 6A cabling to 10 GbE while retaining 1 GbE switch compatibility through auto-negotiation. It is not for environments that require SFP+ fibre connectivity, multi-port density in a single bracket or PCIe 3.0 and newer electrical signalling.

PCIe 2.1 x8 Electrical Interface

The adapter requires an x8 electrical link running at PCIe 2.1 speed; reduced lane widths will constrain 10 Gbps throughput. Verify the host platform provides an x8 or wider slot with 2.1 signalling before purchase.

Questions about this item

How much heat does the X540T1 generate when running at 10Gbps all day?

The adapter draws modest power typical for a PCIe 2.1 x8 10GBASE-T controller; expect warm but not extreme temperatures inside a server chassis with normal airflow.

What cabling and switch ports must I already have for the RJ45 connector to work?

Cat 6A cabling and a switch port that supports 10GBASE-T or auto-negotiates down to 1GbE are required for the single RJ45 link.

Will the PCIe 2.1 x8 slot in my older server run this card at full 10Gbps speed?

Yes — the X540T1 is designed for PCIe 2.1 x8 and will negotiate 10Gbps or fall back to 1GbE on legacy switches without needing a newer bus.
