USB connectors
There are five USB connectors on your computer: three at the rear
1 and two on
the front
2. In addition, if you have a Rapid Access keyboard, there are two USB
connectors at the rear of the keyboard. When setting up your computer for the
first time, plug the keyboard and the mouse cables into the USB ports at the rear
of the computer. USB devices, such as a keyboard, mouse, printer, or scanner can
be connected to any one of the available USB connectors. These cables can be
relocated to other USB connectors at a later time if desired.
If you want to move or add a USB device, ensure the computer and operating
system are running. It is also recommended that you move or add one device at a
time.
The two USB connectors on the Rapid Access III keyboard are designed for low-
powered USB devices, such as a mouse or gamepad, only. USB devices that
require more power, such as speakers or an unpowered USB hub, should be
connected to one of the USB connectors on the computer.
Note:
Cable connectors from USB devices are keyed so that they cannot be
connected incorrectly.
