Universal Serial Bus (USB) Ports
There are two USB 3.0 port (USB 0/1) on the I/O back panel, and a Type A USB 3.0 header
(USB 2) on the motherboard to provide front access USB connection. The onboard headers
can be used to provide front side USB access with a cable (not included).
Ethernet Ports
Two Ethernet ports (LAN1, LAN2) are located on the I/O backplane. These Ethernet ports
support 10GbE LAN connections on the motherboard. In addition, an dedicated IPMI LAN that
supports GbE LAN is located above the USB 0/1 ports on the backplane. All Ethernet ports
accept RJ45 type cables. Please refer to the LED Indicator Section for LAN LED information.
