Input/Output Interfaces

5.6Universal 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, these systems support a media reader accessory that uses two USB ports through a system board header connection. The USB

2.0controller provides a maximum transfer rate of 480 Mb/s. Table 5-5 shows the mapping of the USB ports.
