Universal Serial Bus (USB)
Two USB 2.0 ports (USB 0/1) are located
on the I/O back panel. In addition, a
Type-A connector is also located on
the motherboard to provide front USB
3.0 support (USB 2). (Cables are not
included.) See the tables on the right and

Ethernet Ports
Two Gigabit Ethernet ports (LAN1 and LAN2) are located on the I/O back panel on
the motherboard. These Ethernet ports support 1GbE LANs on the motherboard.
In addition, an IPMI-dedicated LAN is located above USB 0/1 ports on the back
panel. All of these ports accept RJ45 cables. Please refer to the LED Indicator
section for LAN LED information.
Infi niBand Connector (Optional for X10DRT-LIBF/LIBQ)
An optional Infi niBand connector with FDR/QDR support is located on the I/O back
panel on the X10DRT-LIBF/LIBQ. This connector provides data interconnectivity
within the same computer and among different computers. It is used in High-
Performance Computing (HPC) platforms featuring very high throughput with very
low latency. See the layout below for the location.
