CAUTION

THIS USB HUB IS RATED TO ALLOW FOR 1.5 AMPS OF CURRENT WHEN BUS-POWERED (WITHOUT ANY EXTERNAL POWER ADAPTER). BEFORE CONNECTING ANY DEVICES TO THE USB HUB, ENSURE THAT THE TOTAL MAXIMUM CURRENT DRAW OF EACH OF THE DEVICES ADDED TOGETHER IS LESS THAN THE CURRENT RATING OF THE USB HUB AND THE COMPUTER’S POWER SUPPLY. FAILURE TO DO SO MAY DAMAGE THE PC, THE USB HUB, AND/OR ANY DEVICES CONNECTED TO THE USB HUB.

IF YOU ARE USING A LARGE NUMBER OF DEVICES OR VERY POWER-INTENSIVE USB DEVICES, AN EXTERNAL DC POWER ADAPTER WITH A RATING OF UP TO 5V/3.5A MAY BE USED TO PROVIDE ADDITIONAL CURRENT.

Troubleshooting

USB Hub does not work (Power LED not lit):

•Check the connection between the computer and hub

•Try connecting the hub to a different USB port on the computer

One or more devices connected to the hub are malfunctioning:

•If there are multiple devices connected to the hub, try disconnecting the most recently connected devices until the problem goes away

•Try restarting the computer, or reconnecting the USB hub to the computer

•If too much power is being consumed by any of the devices, you may need to use an external DC power adapter to power the USB hub

The computer displays an error that the USB bus is drawing too much current:

•You may need to use an external DC power adapter to power the USB hub. The power adapter should be a switching type with a rating of up to 5V/3.5A
