Dual-port Gigabit server adapter

The LR-LINK LREC9712HT is a PCI Express x4 network card with two RJ45 copper ports operating at 10/100/1000 Mbps. It is built on the Intel I350AM2 controller and supports IEEE 802.3 standards. The card ships with both low-profile and full-height brackets for flexible installation in servers or workstations.

Virtualisation and multi-OS environments

This adapter suits administrators who need two Gigabit links for virtual machine traffic, link aggregation or separate management networks. It offers I/O virtualisation with up to 32 virtual ports, VPD and MCTP support. Buyers who require 10 GbE speeds, fibre connectors or a single-port card should consider other models.

PCI Express v2.1 x4 interface

The card connects through a PCIe v2.1 x4 slot running at 5.0 GT/s and is compatible with x8 and x16 slots. This interface determines whether the adapter fits the target server or workstation. Verify that the host system provides an available x4, x8 or x16 slot before purchase.

Questions about this item

Will the PCIe 2.1 x4 link saturate before the two 1000 Mbps ports do under sustained load?

The card uses a PCI Express 2.1 x4 interface at 5.0 GT/s, giving ample bandwidth for both Gigabit ports running at full 1000 Mbps simultaneously.

What thermal and acoustic impact should I expect when the adapter runs continuously in a 55 °C environment?

Operating range is 0 °C to 55 °C with no fan on the card; it adds negligible noise and relies on chassis airflow to stay within limits.

Which bracket and slot type must my server already have to install this dual-port adapter?

The kit includes low-profile and full-height brackets and requires an available PCIe x4, x8 or x16 slot.
