Deployment / Use Cases
The Axiom 811546-B21-AX quad-port NIC is ideally suited for server environments requiring multiple network connections for virtualization, network segmentation, or redundant networking configurations. Its four independent ports enable flexible deployment scenarios where network isolation or bandwidth aggregation is necessary.
Common deployment scenarios include virtualization hosts requiring separate network connections for management, storage, and virtual machine traffic; web servers needing multiple network interfaces for load balancing and redundancy; and database servers benefiting from dedicated network paths for replication and client connections. The card's compatibility with twisted pair cabling makes it particularly valuable in environments with existing copper infrastructure.
Virtualization Hosts
Provides dedicated network paths for hypervisor management, virtual machine traffic, and storage networking within virtualized server environments.
Network Segmentation
Enables logical separation of network traffic across different security zones or functional areas while maintaining physical server consolidation.
Physical Profile
The card features a standard plug-in card form factor measuring 5.91 inches in height, 0.55 inches in width, and 2.20 inches in depth. This compact design ensures compatibility with most server chassis while the lightweight construction at 3.84 ounces minimizes mechanical stress on the PCIe slot. The low-profile dimensions make it suitable for both rack-mounted and tower server configurations where space optimization is critical.

FAQ
What type of server is this network card compatible with?
This Axiom network interface card is specifically designed for HP server environments. It features a standard PCIe x4 interface that is compatible with HP servers supporting PCI Express 2.1 slots. The card's dimensions and form factor are optimized for server chassis integration, making it suitable for both rack-mounted and tower server configurations within HP's server ecosystem.
How many network ports does this adapter provide?
The Axiom 811546-B21-AX provides four independent RJ45 network ports. Each port supports Gigabit Ethernet connectivity with 10/100/1000Base-T auto-negotiation. This quad-port configuration enables multiple network connections from a single PCIe slot, allowing for network segmentation, load balancing, or redundant networking configurations without requiring additional expansion cards.
What is the maximum data transfer rate per port?
Each of the four RJ45 ports supports data transfer rates up to 1000 Mbps (1 Gigabit per second) when connected to compatible network equipment. The ports automatically negotiate with connected devices to establish the highest mutually supported speed, functioning at 10 Mbps, 100 Mbps, or 1000 Mbps depending on the connected equipment and cable quality.
What type of cabling does this network card support?
This network adapter supports standard twisted pair copper cabling, specifically Category 5e, Category 6, or higher-grade Ethernet cables. It is compatible with the 10/100/1000Base-T standard, which supports cable lengths up to 100 meters (approximately 328 feet) while maintaining full Gigabit Ethernet performance. The RJ45 ports use standard Ethernet pinouts for straightforward integration with existing network infrastructure.
What PCI Express interface does this card require?
The card requires a PCI Express 2.1 x4 slot for proper operation. This interface provides sufficient bandwidth to support all four Gigabit Ethernet ports simultaneously without performance bottlenecks. While the card physically fits into x4, x8, or x16 PCIe slots, it requires the electrical connectivity of an x4 interface to function correctly and deliver its full 2000 MB/s bandwidth capacity.
What warranty coverage does this product include?
This Axiom network interface card includes a 3-year limited warranty. This warranty covers manufacturing defects and ensures reliable operation in server environments. The warranty period reflects the product's design for continuous operation in data center and enterprise settings, providing assurance of quality and durability for critical networking applications.
