Instruction for Adding Modules (cont'd.) When attaching additional modules to the BusStation™, there is no need to power down your computer, or unplug the BusStation™. Note on Power Consumption USB specifies that each port can only draw a maximum of 500mA of electrical current. If a device draws more than that amount, the Bus Station's built-in "Overcurrent Protection" will shut off that port, and prevent damage to the device and the Bus Station. When you first purchase the BusStation™, it is essentially a 7 port hub. At 500mA for each port, that's a total of 3.5A current. The included power supply provides 4.0A, which is more than enough. Replacing the one-port modules with other non-hub modules poses no power issues. However, if you decide to add a 4-port hub module, you must provide that 4-port hub with additional power. When you purchase a 4-port hub module, it will include a 2.1A power supply necessary for each port to provide 500mA of current. Simply plug the supplied adapter into the rear of the 4-port hub module, and you're done! If you do not connect the 2.1A power adapter to the 4-port hub module, each port on that 4-port hub can only supply 100mA of current. Usually, only low-power devices such as mice and keyboards will run at 100mA. More complex devices such as scanners, modems, and additional hubs require the full 500mA of current. 8
