Deployment / Use Cases
The HP Intel I350-T4 Gigabit Ethernet Card serves multiple roles in modern IT infrastructure. In server environments, it provides additional network ports for virtualization hosts, storage servers, or application servers requiring separate network segments for management, data, and backup traffic.
For workstations and high-performance computing systems, this adapter enables multiple simultaneous network connections for bandwidth-intensive applications, network segmentation testing, or connection to disparate network infrastructures. The card's compatibility with standard twisted-pair cabling makes it suitable for both new deployments and infrastructure upgrades.
Server Connectivity
Ideal for rack-mounted and tower servers needing multiple network interfaces for virtualization, storage networking, or network segmentation.
Workstation Expansion
Provides additional Ethernet ports for engineering workstations, media production systems, or development environments requiring multiple network connections.
Physical Profile
The plug-in card form factor measures 2.52 inches in height and 5.31 inches in depth, designed to fit standard PCI Express slots in server and workstation chassis. The low-profile design ensures compatibility with various system configurations while maintaining adequate cooling for sustained operation.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 2.52" (64 mm), 5.31" (135 mm). This helps confirm rack, shelf, desk, or cabinet fit before installation.

FAQ
What type of PCI Express slot does this network card require?
This HP Intel I350-T4 Gigabit Ethernet Card requires a PCI Express 2.1 x4 slot or any larger PCIe slot (x8, x16) that maintains backward compatibility. The card will physically fit in any PCIe x4 or larger slot and operates at x4 electrical signaling. For optimal performance, install it in a slot that provides adequate bandwidth for the combined throughput of all four Gigabit Ethernet ports.
How many network ports does this adapter provide?
This network card provides four independent RJ-45 Ethernet ports, each capable of operating at 10, 100, or 1000 Mbps speeds. All four ports support auto-negotiation to automatically determine the optimal connection speed with compatible network equipment. The ports function independently, allowing simultaneous connections to different network segments or aggregation for increased bandwidth.
What network speeds does this Ethernet card support?
The HP Intel I350-T4 supports 10/100/1000Base-T network standards, providing connectivity at 10 Mbps, 100 Mbps, or 1000 Mbps (Gigabit) speeds per port. Each port automatically negotiates the highest mutually supported speed with connected network equipment. The PCI Express 2.1 x4 interface provides sufficient bandwidth for all four ports to operate simultaneously at full Gigabit speeds.
Is this network card suitable for server virtualization?
Yes, this adapter is specifically designed for virtualization environments. It includes hardware acceleration features like VMQ (Virtual Machine Queue) and SR-IOV (Single Root I/O Virtualization) support, which improve network performance for virtual machines by reducing CPU overhead and providing direct hardware access. These features make it ideal for hypervisor hosts running multiple virtual machines with demanding network requirements.
What type of cables does this Ethernet card support?
This network adapter supports standard twisted-pair Ethernet cables (Category 5e, 6, or higher) with RJ-45 connectors. It is compatible with both straight-through and crossover cables through auto-MDI/MDIX functionality. The card supports cable lengths up to 100 meters per the Ethernet standard, making it suitable for typical office and data center cabling infrastructure.
What is the warranty coverage for this HP network card?
This HP-branded option includes a one-year parts replacement warranty from HP. If installed in an HP Hardware Product, warranty service may extend to match the remaining warranty period of the host system, up to a maximum of three years from the purchase date.
