11.3.3 Universal Serial Bus (USB) Interface
The main board provides a double-stacked USB port at the rear panel. The front panel fan board (FPFB) provides a
triple-stacked USB port connector at the front panel. These built-in USB ports permit the direct connection of five USB
peripherals without an external hub. If more devices are required, an external hub can be connected to any of the built-
in ports. In addition, there are two internal USB 2.0 supporting Solid State Drive flash storage devices that can dock
onto the main board.
The pin-out for the dual USB connector and the two internal USB is listed in the tables below. The pin-out for the triple
USB connector on the front panel I/O board is listed in Section 14.
