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 DC power (range from +7V to 24V) to the 2-pin Terminal Block
Connector
. The hub was self-powered by this connector.

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.
