Network Interface Controller (NIC)

The server board S875WP1-E supports two Network Interface Controllers (NICs), one that runs at 10/100Mb and is based on the Intel 82562ET NIC and the other that runs at one gigabit and is based on the Intel 82547EI NIC. When looking at the rear of the chassis, the gigabit NIC is at the left (closest to the video port) and the 10/100Mb 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 +3.3 V 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 6 describes the LED states when the board is powered up and the 82562ET 10/100 Ethernet LAN subsystem is operating.
