Dual-port 10Gbps server adapter

The LR-LINK LREC9812BT adds two RJ45 10GbE ports through a PCIe 3.0 x4 slot. It targets administrators upgrading rack-mount or tower servers to 10 Gigabit copper without replacing existing CAT 6a cabling. The card also supports NBASE-T at 2.5 and 5.0 Gbps over CAT 5e for mixed environments.

Thermals and power profile

Operating temperature spans 0 °C to 55 °C with humidity tolerance of 5 % to 95 % non-condensing. The integrated MAC and PHY design keeps power draw low for dense chassis deployments. No Wake-on-LAN function is present, so the ports remain inactive during host sleep states.

Deciding specification

The single factor is the PCIe 3.0 x4 electrical interface delivering 8.0 GT/s bandwidth. Buyers whose motherboards only offer x1 or x2 slots cannot use the card at rated throughput. Systems limited to PCIe 2.0 will also fall short of 10 Gbps line rate.

Questions about this item

How do I install the LREC9812BT and what step is often missed?

Insert the card into a PCIe 3.0 x4 slot — it also fits x8 and x16 — then secure the bracket; the step often missed is attaching the correct low-profile or full-height bracket for your chassis before mounting.

What maintenance or replacement will the LREC9812BT need later?

No scheduled maintenance is required; keep the RJ45 ports dust-free and ensure airflow so the card stays within its 0 °C to 55 °C operating range — replace only if a port fails or the adapter is damaged.

What limit appears first on the LREC9812BT under sustained 10 Gbps loads?

The PCIe 3.0 x4 interface at 8.0 GT/s caps sustained throughput, so the bus bandwidth becomes the bottleneck before the dual 10GBASE-T ports reach their maximum.
