1.10 LAN Subsystem
The LAN subsystem consists of the following:
•
Physical layer interface device. As a manufacturing option, the board includes one of the
following Platform LAN Connect (PLC) devices:
Intel
®
82562EZ PLC for 10/100 Mbits/sec Ethernet LAN connectivity
Marvell Yukon 88E50 for Gigabit (10/100/1000 Mbits/sec) Ethernet LAN connectivity
•
RJ-45 LAN connector with integrated status LEDs
Additional features of the LAN subsystem include:
•
CSMA/CD protocol engine
•
LAN connect interface that supports the 82562EZ
•
PCI Conventional bus power management
Supports ACPI technology
Supports LAN wake capabilities
1.10.1 10/100 Mbits/sec LAN Subsystem
The 10/100 Mbits/sec LAN subsystem includes the ICH6, the Intel 82562EZ PLC, and an RJ-45
LAN connector with integrated status LEDs.
1.10.1.1 Intel
®
82562EZ Physical Layer Interface Device
The Intel 82562EZ provides the following functions:
• Basic 10/100 Ethernet LAN connectivity
• Full device driver compatibility
• Programmable transit threshold
• Configuration EEPROM that contains the MAC address
1.10.1.2 RJ-45 LAN Connector with Integrated LEDs
Two LEDs are built into the RJ-45 LAN connector (shown in Figure 11 below).
