Tips & Hints

A note on power

For improved compatibility, this hub reports to the computer’s operating system that it is self-powered. This is only true when the product is externally powered through its DC socket. For full 500mA per port capability this DC supply must be rated at 5VDC 2A. Note that a DC power supply is not provided with this product.

When a DC supply is not connected, the product is bus-powered and draws all its power from the USB socket it is connected to. Users should be aware of the following:

• The combined loading of all the USB devices connected to the hub cannot exceed the power available from the single USB socket that powers the hub.
• Commonly, up to 4 low-power or self-powered devices can be connected, but no more than 1 bus-powered, full-power device (such as a Hard Disc) should be connected.
• The hub’s power requirement, as reported by the computer’s operating system, may be incorrect.
