Network Interface Controller (NIC)
The server board
The 82562ET is controlled by the
•Integrated IEEE 802.3
•IEEE 802.3u
•Full duplex support at both 10 Mbps and 100 Mbps operation
•Low power +3.3 V device with reduced power in unplugged mode and automatic detection of unplugged mode
•
The 82547EI is controlled by the CSA interface off of the MCH. It supports the following features:
•Basic 10/100/1000 Ethernet LAN connectivity
•Integrated Gigabit Ethernet Media Access Control (MAC) and physical layer (PHY)
•IEEE 802.3
•IEEE 802.3ab
•Low power (less than 350mW in active transmit mode)
•Reduced power in “unplugged mode” (less than 50mW)
•Automatic detection of “unplugged mode”
•Communication Streaming Architecture (CSA) port provides higher throughput and lower latencies resulting in up to 30% higher bus throughput (up to wirespeed)
•Full device driver compatibility
•Programmable transit threshold
•Configuration EEPROM that contains the MAC address
•Teaming and Fail over support
