Product Features
Technical Overview
This NIC card implements the 10/100/1000Base-T Ethernet standard, offering backward compatibility with legacy 10 Mbps and 100 Mbps networks while maximizing performance on modern Gigabit infrastructure. The PCIe 1.1 x1 interface provides sufficient bandwidth for full-duplex Gigabit operation, with a theoretical throughput of 250 MB/s per direction.
The adapter supports twisted pair copper cabling (Category 5e or higher recommended) for cost-effective deployments, with reliable signal transmission over distances up to 100 meters. A single RJ-45 port handles all network connectivity, simplifying cable management and reducing desktop clutter.
Relevant factors for this section include Host Interface, Total Number of Ports, Number of Network (RJ-45) Ports, Media Type Supported. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
Key Product Advantages
The SI-PEX24038-AX delivers essential Gigabit Ethernet expansion in a reliable, server-grade package. Its combination of performance, compatibility, and straightforward installation makes it an ideal solution for adding wired network connectivity to systems where integrated options are unavailable or insufficient.
Performance-Optimized Interface
The PCIe 1.1 x1 host interface ensures the card can sustain full Gigabit speeds without bottlenecking, providing a stable foundation for data-intensive server applications and high-throughput workstation tasks.
- Dedicated bus bandwidth
- Low-latency data path
- No shared resource contention
Universal Cable Support
Compatibility with standard twisted pair cabling means this adapter works with existing network infrastructure without requiring specialized or expensive fiber optic components.
- Uses Cat5e/Cat6 cables
- 100-meter reach
- Cost-effective deployment
Deployment / Use Cases
This single-port Gigabit Ethernet card serves as a practical network expansion solution for various computing environments. Its server designation indicates robust construction and reliability for continuous operation in business-critical applications.
Common deployment scenarios include adding a dedicated management network port to a server, providing wired connectivity to a workstation lacking integrated Ethernet, or serving as a backup network interface in redundant configurations. The card's compact form factor makes it suitable for both tower and rackmount systems with available PCIe x1 slots.
Server Network Expansion
Add a secondary Gigabit port for network segmentation, out-of-band management, or load distribution without consuming higher-bandwidth PCIe slots needed for storage or other expansion cards.
Desktop Connectivity Upgrade
Enable Gigabit networking on older systems or budget builds that ship with only Fast Ethernet (100 Mbps) interfaces, significantly improving file transfer speeds and network responsiveness.
Physical Profile
Measuring 3.94 inches in height, 0.55 inches in width, and 2.17 inches in depth (100 × 14 × 55 mm), this NIC card features a standard half-height bracket design that fits most desktop and server chassis. The lightweight construction at approximately 1.44 ounces (40.82 grams) minimizes stress on the PCIe slot during installation and transportation.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 3.94" (100 mm), 0.55" (14 mm), 2.17" (55 mm), 1.44 oz (40.82 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

FAQ
What type of PCIe slot does this NIC card require?
The Axiom SI-PEX24038-AX requires a PCI Express 1.1 x1 slot or any compatible higher-generation PCIe x1, x4, x8, or x16 slot (it will physically fit and operate in larger slots). The PCIe 1.1 x1 interface provides sufficient bandwidth for full Gigabit Ethernet performance without bottlenecking.
Does this Gigabit Ethernet card support older network speeds?
Yes, this NIC card supports 10/100/1000Base-T auto-negotiation, meaning it automatically detects and connects at the highest mutually supported speed with your network equipment. It will operate at 10 Mbps, 100 Mbps (Fast Ethernet), or 1000 Mbps (Gigabit Ethernet) depending on what your switch, router, or other connected devices support.
What kind of network cables can I use with this adapter?
This adapter supports standard twisted pair copper Ethernet cables (typically Category 5e, 6, or 6A) with RJ-45 connectors. It is designed for use with copper cabling infrastructure and can reliably transmit data over distances up to 100 meters (328 feet) when using properly installed cabling that meets industry standards.
Is this network card suitable for server use?
Yes, the product specifications explicitly list 'Server' under Device Supported, indicating it is designed and tested for server environments. This typically means enhanced reliability for continuous operation, better thermal management, and compatibility with server operating systems and management tools compared to consumer-grade adapters.
What is the warranty period for this Gigabit Ethernet card?
Axiom provides a 3-year limited warranty for the SI-PEX24038-AX network interface card. This warranty covers defects in materials and workmanship under normal use for three years from the date of purchase, offering substantial protection for business and institutional deployments where long-term reliability is essential.
How many network ports does this PCIe card provide?
This is a single-port network interface card, providing one RJ-45 Ethernet port. The total number of ports is 1, with that single port being a standard network (RJ-45) interface. This makes it ideal for adding one additional wired network connection to a system, whether for primary connectivity, a dedicated management network, or backup purposes.
