Dual-port 10Gbps Ethernet adapter

The Lenovo 4XC0F28730 I350-T2 adds two 10Gbps RJ45 ports through a single PCI-Express slot. It targets servers and workstations that need aggregated bandwidth for storage replication or virtualisation traffic.

Sustained throughput on both ports

Each port maintains line-rate 10Gbps under continuous load without throttling. The dual-port design balances sessions across physical interfaces, reducing queue depth during heavy multi-VM or backup workloads.

Low-profile bracket and Intel controller

The card uses a low-profile bracket for 1U and 2U chassis compatibility. An Intel I350 controller handles offloads such as checksum and segmentation, lowering host CPU utilisation during prolonged transfers.

Questions about this item

How much heat or noise does the I350-T2 produce when running continuously at 10Gbps?

The card has no fan and draws power only from the PCIe slot, so it runs silently with minimal heat output during all-day 10Gbps operation.

What cabling and switch ports are needed to use both ports on this adapter?

You need two Cat6a or better RJ45 cables and a switch with two available 10GBASE-T ports to enable both connections.

Will this PCIe card work in an older server that only has PCIe 2.0 slots?

Yes, the I350-T2 is backward compatible with PCIe 2.0 x4 or wider slots, though total throughput will be limited to the slot's bandwidth.
