Before powering ON your Hanabi series switcher, verify all cabling connections are secure and
power connections are in place.

Use the supplied AC cord to connect the OU to AC power supply.
Release the screws at both sides of the panel and lift panel at corners to access power
switches. (Power switches are located inside the OU case.)
When you open the OU there will be two power switches visible that are located by the
OU power supplies as indicated in the figure below. Turn at least one power switch
(POWER1) ON to use your OU. Normally, both power switches should be set to ON at the
same time if you have a redundant power supply (optional).
Shutdown the panel. “HANABI” will appear on the menu display when the power is
properly supplied to the unit.
