LEDIndicatorDescription

The DUB-H7 features eight LED indicators.

•The Power LED indicator is green and lights up when the DUB-H7 is powered on by

using the external power adapter. The DUB-H7 does not run on power supplied from the

computer (bus powered).

•The downstream LED indicators are green and light up when the DUB-H7 is plugged into

the host computer. Each port has one status LED. The LEDs light up to indicate that

port is working.

•When connecting USB cables between USB devices and the DUB-H7, make sure that

the cables are connected securely.

•Remember that when connecting USB 1.1 devices to a USB 2.0 hub or host adapter, the

USB 1.1 device will operate only at USB 1.1 speed.

•The DUB-H7 does not have an on/off switch. It is always on, once the external power

adapter has been plugged into a wall socket or power source.

•Connecting USB 1.1 devices to the DUB-H7 may cause all USB devices connected to

the hub to work at USB 1.1 speed. To ensure 480Mbps throughput for your USB 2.0

devices, do not connect USB 1.1 and USB 2.0 devices to the hub at the same time.

•While using a USB device that includes anAC power adapter, use the included power

adapter to ensure proper power and current supply to that device.

•Please remember to unplug the DUB-H7 properly to ensure that no data loss or corrup-

tion takes place with your operating system.

Tips

Note : If a port becomes overloaded, a “current exceeded” event will take place. The LED

of the port will turn off and the message “USB HUB Current Limit Exceeded” appears on

the monitor. Reset the DUB-H7 by disconnecting it for 5 seconds and then powering it

back on by connecting the AC power adapter.
