1.1 INTRODUCTION
First of all, thank you for purchasing MyWx,MyGx,MyTx,MyZx,DmyWx,S1M series
redundant power supply.
The MyWx,MyGx,MyTx,MyZx,DmyWx,S1M series is a N+1 hot-swappable /
hot-pluggable redundant power supply. It consists of,
The total output is up to your power’s requirements, you can figure out the total
Power’s consumption and check over the specification, the you can find out the
correct configuration.
It delivers full safety redundant (hot-swappable) function and provides the
hot-pluggable feature. In other words, it can offer a more reliable and safer, easy
install / maintain operation in the power energy supply to your system.
Its major function is to deliver the full power and the mean time these power modules
can mutually backup once one of the power modules is defective.
It provides a warning subsystem, include LED display, buzzer alarm, TTL signal etc.,
at the same time, it also indicates the status of the power system.
When all the power modules are at normal condition, it balances the load share and
results the power system increase reliability.
To really discover the power and ease in using the product, we recommend that
you read through this manual carefully.

1.7 INSTALLATION & TESTING
Mount the power system into the system chassis
Attach the connectors to main board by following the main board’s instructions, there
are various on pinouts / connectors in both the power system and main board, 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 maybe “keyed”, so there will be only one possible way to
connect them.
Before applying power source to the system, make sure these are no loose or
incorrect connections. Please check your power system is AC source version or DC
source version, to supply the correct source.
To test the redundancy function, please supply the source to the individual power
modules. If the individual power module. Operates normally, the LED on the module
lits in GREEN, and the external warning LED also lits in GREEN. Now remove the
source from one of the individual power module, 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 blink/RED, the individual LED indicating the power module’s
status will not light. Meanwhile the power system will continue to backup the power
output without affecting the system’s operation.
The warming buzzer will continue sounding, the user can reset the warning buzzer by
pressing the buzzer reset switch.
Turn on the power module which is turned off for testing earlier, the sound of the
warning buzzer will disappear, the external warning LED will turn GREEN again; the
LED indicating the status of power module will light again, you may test other power
module by performing the similar procedure.
1.8 Hot-swap procedures
Please refer to the following when one power module is found defective.
(1) Locate the defective power module by examining the individual LED (if LED is
without light, it indicates the power module is defective).
WARNING:
Please perform the BELOW step carefully; otherwise, it may cause shut down of the
whole system.
(2) Turn off
WARNING:
Please do not remove the defective power module until you have worn gloves to keep
from been burned. This is due to the cover of the power module is used as heat sink
for cooling. Usually, its temperature is around 50-60 degree Celsius under full load
condition.
(3) Remove the defective power module by puling out method.
WATNING:
Please put aside the power module to wait for cooling down. Keep other people from
toughing it until it is cooled.
(4) Replace a new / GOOD power module, insert the power module into the power
system till to the end.
(5) Turn on the new power module.
(6) Check the LED of the power module light GREEN.
(7) Check the LED which indicates the total power system status, that SHOULD be
from blink/RED to GREEN.
(8) If you want to test this new power module and simulate the defective situation,
please refer to Section 1.7 Installation & Testing Section.

1.10 TROUBLE SHOOTING
If you have followed all directions correctly, these should be no problem. Some
common symptoms are: the system doesn’t work, buzzer sound, work for a very short
period etc., please try the following steps to verify and correct it:
1. Check all the connections (correct pinouts, loose connection, wrong direction etc.,)
2. Check for short-circuit or defective peripherals by unhooking each peripheral once
at a time. When the system functions again, you have solved the problem.
3. Once you hear the buzzer sound or see the LED is blinking/ RED, please aware of:
a. If the source is OK.
b. If the load is under the minimum / over. The maximum load of each channel
(please refer the Specification)
c. If Ac / Dc input voltage been selected correctly.
d. If the power cable(s) been well plugged into the Input kit.
Suppose the above condition been happened, please turn off the power system,
await for 2-3 minutes for releasing the protection state, then test it again.
e. If buzzer still sound or the LED shows power module is defective, please
locate which power module is defective, perform Hot-swap procedure at your
proper time, send the defective item to your vendor for RMA operation.
f. If you can not fix the problem, please contact with your vendor for supporting.
