Leoxsys LEO-4GE82571 Four RJ-45 10/100/1000Mbps Dual Gigabit PCIe Network Adapter is a highly integrated and cost-effective 32-bit Gigabit PCIe Ethernet Adapter which is fully compliant with IEEE 802.3, IEEE 802.3u and IEEE 802.3ab specifications.

The Leoxsys LEO-4GE82571 PCI-e x1 Network Card is fully compliant with Microsoft NDIS5, NDIS6 (IPv4, IPv6, TCP, UDP) Checksum and Segmentation Task-offload (Large send and Giant send) features, and supports IEEE 802 IP Layer 2 priority encoding and IEEE 802.1Q Virtual bridged Local Area Network (VLAN).

The above features contribute to lowering CPU utilization, especially benefiting performance when in operation on a network server. Each port provides 10/100/1000 Mbps capable Ethernet, the 4 -port Ethernet card supports full-duplex flow control for maximum data transfer speeds of up to 2000 Mbps.

The Quad Port 10/100/1000 Base Leoxsys LEO-4GE82571  Adapter is a full duplex, dual ported, gigabit Ethernet adapter that can be configured to run each port at 10, 100, or 1000 Mbps data rates. The adapter connects to the system using a PCI or PCI X bus and connects to a network using standard unshielded twisted pair (UTP) cable for distances of up to 100 meters. AIX Network Installation Management (NIM) boot capability is supported with this adapter. The adapter conforms to the IEEE 802.3ab 1000 Base T standard. The adapter also supports jumbo frames when running at the 1000 Mbps speed.

For PCs with PCI Express (PCIe) slots, the Leoxsys LEO-4GE82571 offers the newest technology for maximizing system performance and increasing end-user productivity. Specifically, the Leoxsys LEO-4GE82571 uses auto-negotiation to ensure the adapter runs at the highest available network speed (10, 100, or 1000 Mbps), and it maintains full bandwidth capacity with the dedicated bandwidth of a PCI Express input/output (I/O) bus to provide connectivity you can count on.
