Network Controller

Note: To ensure EMC product regulation compliance, the system must be used with a shielded LAN cable.

The server board uses the Intel® 82546EB Fast Ethernet Controller and supports two 10Base-T/1000Base-TX network subsystems.

The 82546EB controller supports the following features:

•32-bit PCI master interface

•Integrated IEEE 802.3 10Base-T, 100Base-TX and 1000Base-TX compatible PHY†

•IEEE 820.3u auto-negotiation support

•Full duplex support at 10 Mbps, 100 Mbps, and 1000 Mbps operation

•Low power +3.3 V device

On the Altos R700 Server Board, NIC 1 can be used as both a network interface and server management interface.

NIC Connector and Status LEDs

The 82546 controller drives LEDs on the network interface connector that indicate link/activity on the LAN and speed of operation. The green LED indicates network connection when on and TX/RX activity when blinking. The speed LED indicates 1000 Mbps when amber, 100 Mbps when green, and 10 Mbps when off.
