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 bus-powered by
the upstream USB port, this terminal block connector is to
add power to ensure enough power for the 7 downstream
ports.
