Input/Output Interfaces

5.10 Network Interface Controller

These systems provide 10/100/1000 Mbps network support through an Intel 82566 network

interface controller (NIC), a PHY component, and a RJ-45 jack with integral status LEDs. The

82562-equivalent controller integrated into the 82801 ICH component is not used (disabled) in

these systems.

(Figure 5-11). The support firmware for the BCM5752 component is contained in

the system (BIOS) ROM.

The NIC can operate in half- or full-duplex modes, and provides

auto-negotiation of both mode and speed. Half-duplex operation features an Intel-proprietary

collision reduction mechanism while full-duplex operation follows the IEEE 802.3x flow control

specification.

Figure 5-11.

Network Interface Controller Block Diagram

The Network Interface Controller includes the following features:

■

VLAN tagging with Windows XP and Linux

■

Multiple VLAN support with Windows XP

■

Power management support for ACPI 1.1, PXE 2.0, WOL, ASF 1.0, IPMI, AMT 3.0

■

Cisco Etherchannel support

■

Link and Activity LED indicator drivers

The controller features high and low priority queues and provides priority-packet processing for

networks that can support that feature. The controller's micro-machine processes transmit and

receive frames independently and concurrently. Receive runt (under-sized) frames are not passed

on as faulty data but discarded by the controller, which also directly handles such errors as

collision detection or data under-run.

The NIC uses 3.3 VDC auxiliary power, which allows the controller to support Wake-On-LAN

(WOL) and Alert-On-LAN (AOL) functions while the main system is powered down.

✎

For the features in the following paragraphs to function as described, the system unit must be

plugged into a live AC outlet. Controlling unit power through a switchable power strip will, with

the strip turned off, disable any wake, alert, or power mangement functionality.
