Chapter 2 Connecting Peripherals
2.14 USB (USB12, USB34, USB56)
The PCI-7020 board provides up to Six USB (Universal Serial Bus) ports. This gives
complete Plug and Play, and hot attach/detach for up to 127 external devices. The
USB interfaces comply with USB specification Rev. 2.0, and are fuse protected. The
USB interface is accessed through the 5 x 2-pin flat-cable connector, CN9 (USB0, 1),
CN10 (USB2, 3). You will need an adapter cable if you use a standard USB connec-
tor. The adapter cable has a 5 x 2-pin connector on one end and a USB connector on
the other. The USB interfaces can be disabled in the system BIOS setup.
2.15 Case Open (JCASE1)
PCI-7020 provides 2-Pins pin header for case open detection. This function could be
enabled or disabled in the BIOS setting. When the PIN is shorted, it will cause the on
board buzzer to sound.
