About the Universal Serial Bus (USB) Ports

The system provides two low-speed industry-standard Universal Serial Bus (USB) ports for connecting the system to standard USB devices and compatible USB hubs.

Connectivity is provided by the four standard four-pin USB connectors on the back panel of the system. The Sun Type 6 USB keyboard (a Sun Type 5 keyboard with a USB interface), and a Sun USB mouse are supported for direct system I/O and require one 4-pin USB connector each.

The USB ports, connectors J3001 and J3002, operate at a 12-Mbps data transfer rate. See “Reference for the Universal Serial Bus (USB) Connectors” on page 215 for the connector diagram, back panel icon, and pin assignments.
