1.7 INSTALLATION & TESTING
Mount the power supply into the system chassis by using proper mounting tool. The
mounting holes of the power supply should match up with those in the chassis.
Connect the power connectors to the M/B by following the M/B instruction. There is
various on connectors / pinouts in both power supply and M/B. Please ensure to
connect the matched one; otherwise, it will cause une xpected harms.
Connect the remaining power connectors to the various peripherals as needed. These
connectors are “keyed”, so there will be only one possible way to connect them.
Before applying power source to the system, make sure these is no loosed or
incorrect connectors. Double check if all connection to the M/B is matched properly.
Maybe you would like to test the redundancy function before you put back the cover of
your system chassis, then, please power it on. If the power system operates normally,
the individual LEDs on power module and the external warning LED light in GREEN.
Now, remove one power module from the power system, the warning buzzer in the
power system will sound, the external warning LED, which displays the status of the
total power system, will change to be RED, the individual LED indicating the power
module’s status will distinguish. Meanwhile, the power system will continue to backup
the power output without affecting the operation of your computing system.
The warming buzzer will sound continuously. You can reset warning buzzer by
pressing the buzzer reset switch. Insert the power module which is removed for test
earlier. The sound of the warning buzzer will stop; the external warning LED will turn
to be GREEN again; the LED indicating the status of power module will light in
GREEN. Test another power supply by performing the same procedure.
If everything works out fine, then turn off the power system. Now put back the cover of
the chassis and tighten with the screws which you have retained earlier. Now you
have completed the installation of DMRW series redundant power supply.
