Chapter 5: Advanced Motherboard Setup
Ethernet Ports
Two Gigabit Ethernet ports (LAN1/2) are located on the I/O backplane on the motherboard to provide internet con- nections. In addition, a dedicated IPMI LAN port is included located above the USB ports on the backplane to provide KVM support for IPMI 2.0. All these ports accept RJ45 type cables.

Unit Identifier Switch/UID LED Indicator
A Unit Identifier (UID) switch and an LED indicator are located on the moth- erboard. The UID switch is located next to the VGA port on the backplane. The UID LED (LE4) is located next to the UID switch. When you press the UID switch, the UID LED will turn on. Press the UID switch again to turn off the LED indicator. The UID Indicator provides easy identification of a system unit that may be in need of service.
Note: UID can also be triggered via IPMI on the motherboard. For more information on IPMI, please refer to the IPMI User's Guide posted on our website @http://www.supermicro.com.
