1.2 Connector Layout
Figure 1
USB 3.0 Upstream Port USB 3.0 Downstream Port Self Power Input
Type-B connector from
upstream USB 3.0 port. It is
connected from host or
another USB 3.0 hub.
Supports both normal and
screw-lock type USB cables
on Type-B port only.
There are 7 Type-A
connectors for USB 3.0,
USB 2.0 or USB 1.1 devices.
They support normal Type-
A USB cables (non screw
lock).
This 2-pin (one pin for
positive voltage and the
other pin is GND) terminal
block connector is used to
connect strong power to
self-power the hub.
1.3 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. Apply +12V DC power to the DC Jack Connector. The hub is self-powered by
this connector.
3. Connecting USB Host cables: The host cable could be either a standard A-to-
B USB 3.0 cable or an optional A-to-B USB 3.0 screw-lock cable. Please
connect the type-A end connector of the cable to your PC’s host USB 3.0
port, then insert 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.
