Dual-port 10GbE adapter for servers

The Intel X540T2 installs in a PCI Express 2.1 x8 slot and presents two RJ45 ports that auto-negotiate at 100 Mbps, 1 Gbps or 10 Gbps. It targets administrators who need copper-based 10 GbE connectivity for bandwidth-intensive workloads without moving to fibre. The card ships with both low-profile and full-height brackets so it fits a range of chassis.

Requires Category-6A for full reach

Category-6 cabling supports the 10 Gbps rate up to 55 metres while Category-6A extends that distance to 100 metres. The controller handles the physical-layer negotiation so existing 1 GbE switches interoperate immediately, letting you upgrade switches later when budget allows. No SFP modules or optical patch cords are involved.

Sustained throughput at 13.4 W TDP

The Intel Ethernet Controller X540 is rated for a maximum thermal design power of 13.4 W, a figure that reflects continuous 10 Gbps traffic on both ports rather than a brief burst. Server airflow must accommodate that steady heat load, especially when multiple adapters populate adjacent slots. The dual-port design doubles aggregate bandwidth without doubling the slot count.

Questions about this item

Will the 13.4 W TDP become a thermal limit inside a densely packed server chassis?

The adapter is rated at 13.4 W maximum TDP; actual heat depends on airflow and ambient temperature inside your chassis.

How much fan noise does the card add when running at 10 Gbps continuously?

The card itself has no fan; any audible noise comes from the system fans reacting to the 13.4 W heat load.

Which bracket height do I need — low-profile or full-height — for my server?

Both low-profile and full-height brackets are included, so the card fits either form factor without extra parts.
