Universal Serial Bus connectors
Your computer has two Universal Serial Bus (USB) connectors for optional telephony
and multimedia devices. USB devices configure automatically with Plug and Play
technology.
Notes:
1. If you attach a standard (non-USB) keyboard to the keyboard connector, the USB
connectors and devices will be disabled during the power-on self-test.
2. If you install a USB keyboard that has a mouse connector, the USB keyboard
emulates a mouse, and you will not be able to disable the mouse settings in the
IBM Setup Utility program.
USB cables: Use a 4-pin USB cable to connect external devices to USB connectors.
USB technology transfers data at up to 12 megabits per second (Mbps) with a
maximum of 127 external devices and a maximum signal distance of 5 meters (16 ft)
per segment.
USB connectors: See "Input/output connectors" on page 75 for the location of the
USB connectors.
