Network Interface Controller (NIC)
The server board S875WP1-E supports two Network Interface Controllers (NICs), one that runs at
10/100 Mb and is Based on the Intel
Based on the Intel
left (closest to the video port) and the 10/100 Mb NIC is at the right. You can disable either or both
NICs through BIOS Setup.
The 82562ET is controlled by the ICH5-R and supports the following features:
•
Integrated IEEE 802.3 10Base-T and 100Base-TX compatible PHY.
•
IEEE 802.3u auto-negotiation support.
•
Full duplex support at both 10 Mbps and 100 Mbps operation.
•
Low power +3.3V device with reduced power in unplugged mode and automatic detection
of unplugged mode.
•
3-port LED support.
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 10Base-T/100Base-TX/1000Base-T compliant physical layer interface.
•
IEEE 802.3ab auto-negotiation support.
•
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.
NIC Connector and Status LEDs
Two LEDs are built into each RJ-45 LAN connector. For the 82562ET NIC, the yellow LED indicates a
link to the LAN and the green LED indicates the connection speed. Table 5 describes the LED states
when the board is powered up and the 82562ET 10/100 Ethernet LAN subsystem is operating.
