Universal serial bus ports:
The system board in the
Netfinity 5500 contains two universal serial bus (USB)
ports. Each USB port has an external connector on the
rear on the server for attaching devices that previously
used serial, parallel, keyboard, mouse, and game ports.
USB is an emerging serial interface standard for telephony
and multimedia devices. USB technology uses Plug and
Play to determine what device is attached to the
connector. Each USB device is accessed by a unique
USB address. A device called a hub is used to convert the
USB port into multiple attachment points. A hub has
multiple ports where peripherals can be attached. USB
provides 12 megabits-per-second (Mbps) bandwidth with a
maximum of 63 peripherals and a maximum signal
distance of five meters (16 ft.) per segment.
Note
If more than one USB device is to be attached, then
the device must be connected to a hub.
Table 7 shows the pin-number assignments for the USB
connectors.
