2.5GbE PCIe 3.1 adapter

The Intel I226T1BLK is a single-port 2.5GbE network card built on a PCI Express 3.1 x1 interface. It targets desktop PCs and workstations that need more throughput than standard gigabit Ethernet but do not require a full 10GbE upgrade. The low-profile bracket allows installation in compact chassis.

Upgrading from 1GbE on existing copper

This adapter replaces a 1GbE NIC when the network infrastructure already uses Cat5e or better cabling and a 2.5GbE switch or router is present. The jump is worthwhile when file transfers, backups or local streaming saturate the 1Gbps link and a 10GbE overhaul is not justified. It autonegotiates down to 100Mbps or 10Mbps where needed.

Fits a x1 slot and frees bandwidth headroom

The card occupies one PCIe 3.1 x1 slot and connects through a single RJ45 port. Its ventilated bracket aids airflow in tight builds. It offloads interrupt handling and packet steering to specific cores, leaving more CPU cycles for applications. No auxiliary power connector is required.

Questions about this item

Does the Intel I226T1BLK fit a low-profile bracket and a PCIe 3.1 x1 slot?

Yes, the card uses a PCI Express 3.1 x1 low-profile form factor and a single RJ45 connector.

What driver step is often missed when installing the I226-T1 on Windows?

After seating the card in a PCIe 3.1 x1 slot, install the Intel PROSet driver package before connecting the 2.5Gbps Ethernet cable.

How do I clean the RJ45 port on the I226-T1 if dust builds up?

Power down the PC, then use a brief burst of compressed air to clear debris from the single RJ45 connector.
