1.8 INSTALLATION & TESTING
Turn off (Remote off) the on/off switch. Mount the power supply in the system
chassis using the proper mounting hardware, the mounting holes in the power
supply should match with those in the case. Attach the connectors to the M/B by
following the M/B instructions, there are various connectors / pin-outs of both
power supply and M/B. They should match each other; otherwise the
connection will cause undetectable harms.
Attach all the remaining power supply connections to the various peripherals as
needed. These connectors are “keyed”, so there will be only one possible way to
connect them.
Before applying power to the system, make sure there are no loose or incorrect
connections. You do not need to worry about the setting of AC Input voltage
because of the units’ full range features.
Double check that all pin-outs & connections to the M/B are matched properly.
Maybe you would like to test the redundancy function before you put back the
cover of your system chassis. Turn on (Remote on) the on/off switch, you will
notice if the power unit operates properly, individual LEDs and external
warning LED (please refer to Sec. 1.11 for detail explanation) are lit Green.
Then, when you remove one of the power modules, the warning buzzer in the
power system will sound and the external warning LED which displays the
status of the total power supply system will change color to be Red.
