Network card Longshine LCS-8339T PCIe x4 10 Gbit RJ-45

Longshine LCS-8339T PCIe x4 10 Gbit RJ-45 is a single‑port 10 Gigabit Ethernet network interface card for systems with a PCIe x4 slot. The adapter delivers 10 Gbit/s copper connectivity over standard RJ‑45 cabling, enabling high throughput on desktops, workstations and servers that require upgraded network performance without changing existing structured cabling.

Advantages

The card supports full‑duplex 10 Gbit/s operation on a single RJ‑45 port and fits into a PCIe x4 slot while occupying a single expansion position. It provides backward compatibility with lower Ethernet speeds for mixed environments and offers improved latency and data transfer rates for demanding applications. The compact design and standard interface simplify installation in compatible systems.

Suitable for

• Upgrading desktop or workstation network speed to 10 Gbit/s
• Small server deployments and virtualization hosts
• High‑bandwidth file transfers and media streaming
• Network aggregation and edge connectivity in compact racks

Key specifications

• Interface: PCI Express x4 form factor
• Network port: 1 × RJ‑45
• Maximum data rate: 10 Gbit/s full duplex
• Cable type: copper Ethernet (compatible with Cat6a/Cat7 for 10G links)
• Compatibility: standard PCIe x4 slot on desktop, workstation or server motherboards
• Low‑profile bracket support: yes (fits single expansion slot, verify chassis space)

How to use

Install the card into an available PCIe x4 slot on a powered‑off system and secure it with the expansion slot screw. Connect an appropriate copper Ethernet cable to the RJ‑45 port and to the network switch or router that supports 10 Gbit/s operation. Power on the system and install any required drivers provided by the operating system or vendor to enable full functionality and link negotiation. Verify the link speed and duplex settings in the operating system network configuration or management utility.

Recommendations

For reliable 10 Gbit/s links, use Cat6a or higher quality copper cabling and ensure connected switches or transceivers support 10GBASE‑T. Confirm that the host system’s PCIe lanes and power delivery meet the card’s requirements; consult motherboard documentation if uncertain. Update drivers and firmware to maintain compatibility and performance.
