The 4-Port 10/100/1000 Base-TX PCI Express Adapter is a PCI Express (PCIe), full duplex, four ported, Gigabit Ethernet adapter that can be configured to run either port at 1000, 100, or 10 Mbps data rate. This adapter interfaces to the system through a PCIe bus and connects to a network using a 4-pair CAT-5 Unshielded Twisted Pair (UTP) cable for distances of up to 100 meters. The adapter conforms to the IEEE 802.3ab 1000Base-T standard. The 5717 also supports jumbo frames when running at the 1000 Mbps speed.

The adapter provides the following features:

• Supports interrupt moderation to deliver increased performance while significantly reducing central processing unit (CPU) utilization
• Allows quad-port operation in x4, x8, x16 slots, and each port operates without interfering with the other
• Each port operates without interfering with the other
• Auto-negotiation, full-duplex (half-duplex available for 10/100)
• Integrated media access control (MAC) and physical layer (PHY)
• Supports Fast EtherChannel (FEC) and Gigabit EtherChannel (GEC) when used with capable switch
• Supports IEEE 802.3ad Link Aggregation control protocol when used with capable switch
• IEEE 802.1Q VLANs, IEEE 802.3 (z, ab, u, x) flow control support, IEEE 802.1p
• TCP checksum offload -- transmission control protocol (TCP), Internet Protocol (IP) for IPv4
• TCP Segmentation Offload (TSO) / Large Send Offload (LSO)
• Bus width x4 lane; operable in x4, x8, or x16 slots
• Bus speed (x4, encoded rate) 10 Gbps unidirectional and 20 Gbps bidirectional
• EEPROM SPI and single EEPROM support
• Interrupt levels INTA and MSI (requires system and software support for MSI)
• IEEE 802.3ab
• Hardware certifications FCC B, UL, CE, VCCI, BSMI, CTICK, MIC
• Four RJ-45 connectors
• LEDs on each port identifying speed and link activity
• Compliant with European Union Directive 2002/95/EC on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment
