5 8 9 Ethernet connectors (RJ-45)
Used to attach an Ethernet cable for a LAN. Each Ethernet connector has two status LEDs to help you
identify the Ethernet connectivity, activity, and connection speed.
Notes:
• The Ethernet connector 0 (callout 9 ) marked with “MGMT” is for system management. If you want to use
remote management functions, you need to connect an Ethernet cable to the Ethernet connector 0.
• The Ethernet connector 0 for system management is 82574L by default. If you have selected share
mode for the 82574L Ethernet connector in the Setup Utility program, you can use the connector
as an ordinary Ethernet connector with 100 Mbps network connectivity. However, teaming with other
Ethernet connectors is not supported if the management Ethernet connector is used as an ordinary
Ethernet connector. For detailed information about setting the mode of the Ethernet connector for system
management, see “Setting the mode of the Ethernet connector 0” on page 59
