USB Connectors
There are three USB ports (USB1 and USB2) on the system board that
permit connection of USB peripheral devices directly to the system
without having to use an external hub. If more USB devices are needed,
connect an external hub to either USB port.
✍
There is a USB port (USB3) on the Fax/Modem card (accessible from the rear panel), and a
USB port (USB4) on the front panel. These connectors are identical to USB1 and USB2.
