Product information

Description

The StarTech.com ST1000SPEX43 is a 4-port PCIe Gigabit network adapter card that adds four independent Gigabit RJ45 Ethernet ports to a client, server or workstation using a single PCI Express slot. It features the Realtek RTL8111G chipset and supports full-duplex flow control, providing up to 1000 Mbps in each direction (2000 Mbps total) for reliable wired connectivity in business and virtualised environments.

Advantages

This PCIe network card delivers four separate Gigabit Ethernet interfaces in one compact card, enabling connectivity to multiple networks without requiring multiple expansion slots. The Realtek RTL8111G chipset is designed for stable performance and compatibility with a wide range of operating systems. The adapter supports high-throughput full-duplex operation and is a cost-effective solution for SMB and enterprise use cases that need additional NICs, including some virtualised setups (verify VM software chipset compatibility).

Suitable for

Upgrading servers or workstations that require multiple Ethernet ports
High-bandwidth workstations needing separate network connections
Small and medium business networks and branch offices
Virtualised environments that require multiple physical NICs (check compatibility)

Key specifications

Model: StarTech.com ST1000SPEX43
Chipset: Realtek RTL8111G
Interface: PCI Express (PCIe)
Ports: 4 × Gigabit RJ45
Maximum data transfer rate: 2000 Mbit/s (1000 Mbps each direction)
Networking standards: IEEE 802.3, IEEE 802.3u, IEEE 802.3ab
Connectivity technology: Wired Ethernet

How to use

Install the card into an available PCI Express slot on a powered-off system following standard electrostatic discharge (ESD) precautions. Secure the card in the chassis, connect the Ethernet cables to the RJ45 ports, and power on the computer. Install or update drivers as required by the operating system; many systems will detect the Realtek RTL8111G chipset automatically, but download the latest drivers from the vendor if needed. Configure network settings in the operating system or management software to assign IP addresses and routing as required.

Usage recommendations

Ensure your server or workstation has an available PCIe slot with sufficient lane support and that your operating system and virtualisation software support the Realtek RTL8111G chipset before deployment. For virtualised environments, verify compatibility with your VM hypervisor. Keep drivers up to date and use quality Ethernet cables and switches to maintain optimal throughput.
