FAQ
What type of expansion slot does this network card require?
This card requires a PCI Express 2.0 x4 expansion slot. The PCIe 2.0 x4 interface provides sufficient bandwidth for dual Gigabit Ethernet ports, delivering up to 2000MB/s of throughput. It is backward compatible with PCIe 2.0 x4 slots and will function in compatible PCIe slots, though optimal performance requires the specified interface.
How many network ports does this card provide?
The card provides two RJ-45 network ports. This dual-port configuration allows you to add two separate Gigabit Ethernet connections using only one expansion slot, making it efficient for servers or workstations that need multiple network interfaces without consuming additional PCIe slots.
What network speeds does this Ethernet card support?
The card supports 10/100/1000Base-T network technology, which means it can operate at 10Mbps, 100Mbps, or 1000Mbps (Gigabit) speeds depending on your network equipment and cabling. It automatically negotiates the highest available speed with connected switches or routers, with a maximum data transfer rate of 1000Mbps over twisted pair cabling.
What type of cabling is compatible with this network card?
The card is compatible with standard twisted pair Ethernet cabling (Category 5e or higher recommended). It supports cable distances up to 100 meters (328 feet) while maintaining Gigabit Ethernet performance. This compatibility with common twisted pair cabling makes it easy to integrate into existing network infrastructure without specialized cables.
Is this card suitable for server deployment?
Yes, this card is specifically designed for server deployment. The device supported specification lists 'Server,' and its dual-port configuration, Intel chipset reliability, and included half-height/full-height brackets make it well-suited for adding network capacity to servers in data center, office, or rack-mounted environments.
What mounting options are included with the card?
The package includes both half-height and full-height mounting brackets. These brackets allow the card to be installed in different chassis sizes—half-height brackets for compact server or small form factor systems, and full-height brackets for standard tower servers or larger chassis. This flexibility ensures compatibility with various system configurations.
