Installation
1.Plug the AC adapter into a wall outlet or surge suppressor. Plug the DC connector into the DC power jack found on the side of the Hub.
Note: The Hub may be used without the power supply when connecting low-power devices such as keyboards and mice. Remove the USB A cable connector from its built-in storage bay, then plug it into the downstream port of your computer, or downstream port of another hub (see Fig. 1).
Important Note: The Hub must be connected to a USB 2.0-compliant host in order to function in high-speed mode (480Mbps data rate). If the Hub is connected to a USB 1.1-compliant host, it will operate only in low-speed or full-speed mode (1.5Mbps/12Mbps).
