LED indicator
•
The Power LED indicator is blue and lights up when the DUB-H4 is powered on by
using the external power adapter or by running on power supplied from the
computer (bus powered).
•
If a port becomes overloaded, a "current exceeded" event will take place. The LED
will go off and the message "USB HUB Current Limit Exceeded" appears on the
monitor. Reset the DUB-104 by disconnecting the power adapter (if used) or
disconnecting the dongle from the PC for 5 seconds and then powering it back on
by connecting the AC power adapter or reconnecting the dongle to the PC.
Tips
•
When connecting USB cables between USB devices and the DUB-104, 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 not work at USB 2.0 speeds.
•
The DUB-104 does not have an on/off switch. It is always on once the external
power adapter has been plugged into a power source or the dongle has been
connected to a PC's USB port.
•
Connecting USB 1.1 devices to the DUB-104 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, don't connect USB 1.1 and USB 2.0 devices to the hub at
the same time.
•
D-Link recommends that while using a USB device that includes an AC power
adapter, that you use the power adapter to ensure proper power and current supply
to that device.
•
Please remember to unplug devices properly to ensure that no data loss or
corruption takes place with your operating system.
