Network card ALLNET ALL0139v2-2-10G-TX Dual‑port Copper RJ45 PCIe 3.0

The ALLNET ALL0139v2-2-10G-TX is a dual-port copper network card that provides two RJ45 10 Gigabit Ethernet ports and fits into a PCIe 3.0 slot. Intended for servers and workstations, this network adapter delivers high-speed wired connectivity for data transfer, virtualization, storage networks and other high-performance networking tasks. The card supports standard 10GBASE-T connections over copper cabling for environments that require reliable, low-latency 10 Gbps links.

Advantages

The dual-port design enables two independent 10 Gbps connections or link aggregation for increased throughput and redundancy. Installation into a PCIe 3.0 slot ensures full utilization of available bandwidth while maintaining compatibility with common server and workstation platforms. The copper RJ45 interfaces allow the use of existing Cat6a/Cat7 cabling infrastructure, reducing deployment complexity compared with fiber solutions. The adapter is suitable for consistent, low-latency performance in storage access, virtualization and high-throughput data transfers.

Suitable for

• Upgrading servers and workstations to 10 Gigabit copper networking
• Virtualization hosts requiring higher network throughput
• Storage networks and NAS systems with heavy data transfer demands
• High-performance computing clusters and database servers
• Link aggregation and redundant network paths

Key specifications

• Interface: Two RJ45 ports supporting 10GBASE-T, 1000BASE-T and 100BASE-TX
• Bus: PCI Express 3.0 x8 (backward compatible with x4/x16 slots)
• Data rate: Up to 10 Gbps per port
• Cable type: Compatible with Cat6a/Cat7 twisted-pair copper cabling for 10G links
• Form factor: Low-profile bracket included for standard and low-profile chassis
• Features: Support for link aggregation, jumbo frames and hardware offload capabilities
• Operating temperature range: Typical server-room operating limits (refer to vendor documentation for exact values)

How to use

Power off the system and install the network card into an available PCIe 3.0 slot, securing the bracket to the chassis. If required, replace the full-height bracket with the included low-profile bracket to fit smaller enclosures. Connect Cat6a or Cat7 Ethernet cables to the RJ45 ports and to the network switch or patch panel. Power on the system and install the appropriate drivers or let the operating system detect and configure the adapter automatically. Configure network settings in the operating system or management interface, and set up link aggregation or VLANs as needed for your environment.

Usage recommendations

For reliable 10G performance, use shielded Cat6a or Cat7 cabling and ensure switch ports support 10GBASE-T. When deploying in rack servers, verify airflow and thermal conditions to avoid overheating; consider assigning one high-bandwidth service per port or using link aggregation to balance traffic. Keep firmware and drivers up to date for best compatibility and performance.
