About the USB Ports

The port is accessible by connecting an RJ-45 serial cable to the back panel serial port connector. For your convenience, a serial port adapter (part number 530-2889-03) is included in your Sun Fire V490 server ship kit. This adapter enables you to use a standard RJ-45 serial cable to connect directly from the serial connector on the back panel to a Sun workstation, or to any other terminal that is equipped with a DB-25 serial connector.

For the serial port location, see “Locating Back Panel Features” on page 16. Also see Appendix A.

The system’s back panel provides two external Universal Serial Bus (USB) ports for connection to USB peripheral devices such as:

■Sun Type-6 USB keyboard

■Sun opto-mechanical three-button USB mouse

■Printers

■Scanners

■Digital cameras

For USB port locations, see “Locating Back Panel Features” on page 16.

The USB ports are compliant with the Open Host Controller Interface (Open HCI) specification for USB Revision 1.0. Both ports support isochronous and asynchronous modes. The ports enable data transmission at speeds of 1.5 Mbps and 12 Mbps. Note that the USB data transmission speed is significantly faster than that of the standard serial ports, which operate at a maximum rate of 460.8 Kbaud.

The USB ports are accessible by connecting a USB cable to either back panel USB connector. The connectors at each end of a USB cable are different, so you cannot connect them incorrectly. One connector plugs in to the system or USB hub; the other plugs in to the peripheral device. Up to 126 USB devices can be connected to the bus simultaneously, through the use of USB hubs. The Universal Serial Bus provides power for smaller USB devices such as modems. Larger USB devices, such as scanners, require their own power source.

Both USB ports support hot-plugging. You can connect and disconnect the USB cable and peripheral devices while the system is running, without affecting system operations. However, you can only perform USB hot-plug operations while the operating system is running. USB hot-plug operations are not supported when the system ok prompt is displayed.
