Hardware Installation
JP3 is used to select the power of the PS/2 keyboard, PS/2 mouse ports and USB
11-10 port. Sel5V_standby will allow you to use the PS/2 keyboard or
PS/2 mouse or USB port to wake up the system.

Important:
If you are using the Wake-On-USB Keyboard/Mouse function for 2 USB
ports, the +5V_standby power source of your power supply must sup-
port
≥ 1.5A. For 3 or more USB ports, the +5V_standby power source of
your power supply must support ≥ 2A.
By default, the PS/2 port supports PS/2 keyboard only. If you intend to
connect a PS/2 mouse, you must set JP3 to 2-3 On. This will support
the auto-swap function allowing the system to auto-detect the PS/2 de-
vice.
To allow the system to detect devices that may be incorrectly plugged to
the wrong port on the cable, set JP3 to 2-3 On. Setting JP3 to 2-3 On
will enable the auto-swap function allowing you to use the devices with-
out having to replug the devices.
