Connectors
The 10/100Base-T interfaces are standard 8-pin RJ45 jacks. They are available at the front of the
EPIC/PM through the multi-functional Connector X21 (Intel® 82562) and Connector X5 (Intel®
82551ER).
To find the location of the Ethernet interfaces, please see the
Appendix E: Connector Layout
chapter.
The following table shows the pin-out of the Ethernet connector.

Configuration
The onboard LAN controller can be enabled or disabled in the BIOS Setup Utility. Additionally it is
possible to enable the onboard LAN PXE boot ROM to allow the system to boot up via a network
connection from a PXE boot server. Refer to the I/O Device Configuration Submenu in the
Appendix B:
BIOS Operation
chapter for additional information on configuration.
