Zippy RPU-6400F-RV2S - Manual (Page 22)

IMPORTANT: If you try to convert the power supply from for ATX system use to for normal AT
system use, please refer the following steps:
1. Source the wires converter (20 pins connector 6 pins connectors P8, P9, P11, P12).
P8, P9 for normal AT motherboard
P11, P12 for 3.3V DC output
Convert the 20 pins connector to 6 pins connector.
2. The selector for DEC ALPHA system & INTEL system should be selected as DEC ALPHA
system. (Please refer the instruction sheet.)
3. If you short the white and black wires (for DC on / off switch operation use) for ATX
system by using the screw-on connector, then please recover back to original design. The
on / off switch operation is controlled by the on / off switch.
Before applying power to the system, make sure there are no loose or incorrect
connections. The input voltage has been set to the correct voltage ( 110 / 220 V, the voltage
selector are on the rear side ), double check that all connection to the motherboard are properly
matched.
Maybe you would like to test the redundancy function before you put back the cover
of your system chassis. Turn on the main on/off switch ( if your power supply‘s main on/off wire
lead is black and white color, which means the power supply on / off control is design by using
the DC current, please refer to Sec. 1.8 for installing guide), and the individual power supply's
on/off switches ( on the rear side ), you will notice that if the power unit is operating properly,
then individual LEDs , external warning LEDs ( Please refer to Sec. 1.9 for detail explanation )
are lit GREEN, now turn off one of the power supplies' on/off switch, 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 ( Please note, not every model has this
design, some of those models LED has flashing design ), the individual LEDs ( both on the
rear side or on the front control panel ) indicating the power supply's status will not light.
Meanwhile the power system will continue to backup the power output without affecting the
computer system's operation.
The Warning Buzzer will continue sounding, the user can reset the Warning Buzzer by pressing
the buzzer reset switch at the rear side, refer to the drawing on Sec. 1.3, or use the reset switch
which can be found on the front control panel of the system chassis, the reset switch can be
connected by wires lead provided from the power supply system (Please refer to Sec. 1.9).
Turn on the power supply which is turned off for testing earlier, the sound of the Warning
Buzzer will disappear, the external warning LED will turn GREEN again ( or not flashing ), the
LED indicating the status of the power supply will light again, test another power supply by
performing the similar procedure.
If you use the power defective signal, there is a two pins connector ( refer to the drawing on Sec.
1.3 and table on Sec. 1.9 ), it should be connected to the PMC card properly, please refer the
PMC User's Manual.
If everything works out fine, then turn off the power supplies and the main on / off switch, now
put back the cover of the case and tighten them with the screws which you have retained earlier.
Now you have completed the installation of the RPX redundant power supply system.
