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.
