Model 1117
7-Port USB Hub
System Contents
• Model 1117 7-port USB Hub (with stand)
• 2.5’ USB cable for connection to a computer
• User Manual
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.
Setup & Operation
1. Connect the square (Type “B”) connector of the
included USB cable to the USB hub.
2. Connect the flat (Type “A”) connector of the cable to
one of the computer’s USB ports.
3. The red power LED should light. The USB hub should
automatically be detected by the computer. Allow the
computer to completely install the device. It should
indicate when it has completed.
4. You may now begin connecting devices to the hub
one at a time. Use the 7 USB ports on the USB hub as
you would the USB ports on the computer. The
computer may automatically detect connected devices
or it may require drivers for certain devices. Refer to the
instructions that come with those devices for support
regarding their installation.
