Input/Output Interfaces
5.6 Universal Serial Bus Interface
The Universal Serial Bus (USB) interface provides asynchronous/isochronous data transfers with
compatible peripherals such as keyboards, printers, or modems. This high-speed interface
supports hot-plugging of compatible devices, making possible system configuration changes
without powering down or even rebooting systems.
These systems provide ten externally-accessible USB ports; four front panel USB ports (which
may be disabled) and six USB ports on the rear panel. In addition, the SFF and CMT form factors
support a media reader accessory that uses two USB ports through a system board header
connection. The USB ports are dynamically configured to either a USB 1.1 controller or the USB
2.0 controller depending on the capability of the peripheral device. The 1.1 controllers provide a
maximum transfer rate of 12 Mb/s while the 2.0 controller provides a maximum transfer rate of
480 Mb/s. Table 5-5 shows the mapping of the USB ports.
