+12V DC Jack Power Connector: A DC12V AC adapter is supplied with this product. The AC adapter’s output has to
be connected to here.
USB 3.0 Upstream Connector (w/ Screw Lock):Type-B connector from upstream USB 3.0 port. It is connected from
host or another USB3.0 hub. The connector is compatible with either non-Screw-Lock or Screw-Lock (optional) type
cables.
USB 3.0 Downstream Connectors (w/ Screw Lock): There are 4 Type-A downstream USB 3.0 connectors. They
should be connected to the USB devices with non-Screw-Lock or Screw-Lock (optional) cables.
3. HARDWARE INSTALLATION
1. Use static electricity discharge precautions.
Remove possible static discharge potential from any objects that the hub may come in contact with before
installation. This can be accomplished by touching a bare metal chassis rail after you have turned off the power.
2. Attaching the AC power adapter.
3. Connecting USB Host cable: The host cable is a standard A-to-B USB 3.0 cable (or an optional Screw-Lock type
cable). Please connect the type-A end connector of the cable to your upstream USB port, then connect the type-B
end connector to this hub. Since the USB hub is plug-and-play, you don’t have to turn off your host computer when
installing the hub.
Note: In some cases, you will see an error message said that the USB Hub caused the USB bus power over the
current limit, please ignore this message since the hub is hot plug and its power capacitor will cause a very short period
of current. It will NOT affect your USB function.
4. Connect the USB devices to the downstream ports of this hub. You can use either non-Screw-Lock or Screw-Lock
type (optional) cables. This hub supports both USB 3.0 and USB 2.0 devices. Since the USB 3.0 connectors are
capable of plugging in the standard USB2.0 or USB3.0 cable, it supports both devices directly.
5. Mount your hub on the wall if required.
