AT Keyboard Connector (J2)

Poly-fuse Over Current Protection

The poly-fuse protects the system from dangerous voltages the system might be
exposed to via the keyboard or USB connectors. In case of such exposure, the poly-
fuse will immediately be disconnected from the circuit, just like a normal fuse. After
being disconnected for a certain period of time, the poly-fuse will return to its
normal state, after which the keyboard or USB can function properly. Unlike
conventional fuses the poly-fuse will not have to be replaced, relieving the user
wasted time and inconvenience.

USB Kit Connector (CN1) A through C

The USB Kit connector is a combination of of USB, PS/
2 mouse, and Infrared functions grouped on the same
connector. The USB Kit (Figure 1-5) is installed in a back
panel of the chassis and is connected to the USB Kit
connector with an 18-pin cable.

A. Infrared Connector

If the IR Address Select function in BIOS's Integrated
Peripherals menu is not set at disabled, the COM2 port
will support IR functions. (See Section 3-7)
