1.11 LAN Subsystem
NOTE
The D915GAV board provides a 10/100 Mbits/sec LAN subsystem. The D915GAG board supports
a manufacturing option for one of the following:
• Gigabit (10/100/1000 Mbits/sec) LAN subsystem
• 10/100 Mbits/sec LAN subsystem
• No 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
⎯ Marvel Yukon 88E50 for Gigabit (10/100/1000 Mbits/sec) Ethernet LAN connectivity
(D915GAG board only)
• 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
