1-18 System Overview

Network Controller

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

The server board uses two Intel ® 82550PM Fast Ethernet Controllers and supports two 10Base- T/100Base-TX network subsystems.

The 82550 PM controller supports the following features:

!32-bit PCI, CardBus master interface

!Integrated IEEE 802.3 10Base-T and 100Base-TX compatible PHY

!IEEE 820.3u auto-negotiation support

!Chained memory structure similar to the 82559, 82558, 82557 and 82596

!Full duplex support at both 10 Mbps and 100 Mbps operation

!Low power +3.3 V device

!IP checksum off-loading

On the system board, NIC 1 can be used as both a network interface and server management interface.

NIC Connector and Status LEDs

The 82550 controller drives LEDs on the network interface connector that indicate link/activity on the LAN and 10- or 100-Mbps operation. The green LED indicates network connection when lit and TX/RX activity when blinking. The yellow LED indicates 100-Mbps operation when lit.
