Each of the Ethernet ports can be connected by using:
v CAT5e (or later) UTP cables for 1000 Mbps network attachment
v CAT5 or CAT3 UTP cables for 100 Mbps or 10 Mbps network attachment
The cables are attached to the copper RJ45 connectors. Each port is independent of one another and
supports full-duplex or half-duplex. The half-duplex mode does not support a speed of 1000 Mbps.
The adapter provides the following features:
v Supports interrupt moderation to deliver increased performance while significantly reducing processor
utilization
v Supports dual port operation in almost any PCIe slot, except x1
v Supports auto-negotiation, full-duplex only
v Supports integrated media-access control (MAC) and physical layer (PHY)
v Supports Fast EtherChannel (FEC) with the existing software
v Supports gigabit EtherChannel (GEC) with the existing software
v Supports IEEE 802.3ad (Link Aggregation control protocol)
v Supports IEEE 802.1Q VLANs
v Supports IEEE 802.3 z, ab, u, x flow control support
v Supports IEEE 802.1p
v Supports IEEE 802.3ab for TX
v Supports TCP checksum offload transmission control protocol (TCP), user datagram protocol (UDP),
Internet Protocol (IP) for IPv4 and IPv6
v Supports TCP segmentation or large send offload
v Supports EEPROM-SPI and single EEPROM
v Supports interrupt levels INTA and MSI
v Hardware certifications FCC B, UL, CE, VCCI, BSMI, CTICK, MIC
v Network Controller (MAC) Intel 82571EB
v Compliant with European Union Directive 2002/95/EC on the Restriction of the Use of Certain
Hazardous Substances in Electrical and Electronic Equipment
