ZIPPY M1S2 series User manual

1.1 INTRODUCTION
First of all, thank you for purchasing M1S2 series redundant power supply for 1U.
The M1S2 is a 1+1 hot-swappable / hot-pluggable redundant power supply. It consists
of,
1) complete metal frame
2) compact size power module
3) backplane
The M1S2 series redundant power supply offer a maximum 400/500 watts of output
power. The power module is in compact size, and built-in a 40mm ball bearing DC fan
for better ventilation. Each power module is designed with 5 outputs (+3.3V, +5V,
+12V, -12V, and +5Vsb) circuits, and compliant to ATX12V. All you can see on the
backplane is just passive components and this is the key point for longer MTBF.
The M1S2 series offer a warning sub-system, including LED display, buzzer alarm,
TTL signal, It guides user the fast way to find out the power supply and DC fan status.
When all the power modules operate normally, it balances the load share through its
parallel design, which increases the reliability of power system.
To really discover the power system and ease in using it, we recommend you to read
through this manual carefully.

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 unexpected 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 M1S series redundant power supply.

1.8 Hot-swap procedures
Please refer to the following when either power module is defective.
1) Locate the defective power module by examining the individual LED (if LED is
distinguished, it indicates the power module is defective).
*** WARNING:
Please perform the following step carefully; otherwise, it may cause the whole system
shutdown.
*** 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.
2) Loose the screws of power module bracket.
3) Plug out the defective power module.
*** WARNING:
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) Check the LED of the power module, which should be in GREEN.
6) Check the warning LED indicating the status of total power system, which should
be in GREEN.

7) Tighten the screws of the power module.
8) If you want to test this new power module and simulate the defective situation,
please refer to Section 1.7 Installation & Testing.
Remarks: If the DC fan of the power module fails, you have to replace the power
module. Please follow the Hot-Swap Procedures for replacement.

1.10 SINGLE-MODE and REDUNDENT-MODE
The power supply has two working modes depending on the quantity of power
module inserted, SINGLE-MODE and REDUNDENT-MODE.
1) SINGLE-MODE (only one module inserted and power on)
Notice items:
a) When only one module inserted the detect circuit will assume the other
empty module is Dummy. In this mode, power supply is working at only
one module and without any alarming signals. When module failed, the
power supply shut down.
b) When only module is working then changing to dual modules (Redundant)
working status. Just insert another power module then power on it. There
is no need to power off the system. The detect circuit will assume the
power supply recover the redundant functions. All alarming signals are
functionally when two modules inserted.

c) If two modules inserted, but only power on one power module. The detect
circuit will judge the other module is abnormal (no output) then send
alarming signals.
2) REDUNDENT-MODE
In this mode two modules have to inserted and power on. Any one module
failed the other module will continue working and detect circuit send out the
alarming signals. Alarming singles can be removed by replacing a new power
module or user can disable it.
1.11 TROUBLE SHOOTING
If you have followed these instructions correctly, it should function normally.
Some common symptoms are, the system doesn’t work, buzzer alarms, shutdown
after running a very short period,…etc. If so, please check the following steps to verify
and correct it.
1) Check all connection (if pinouts is correct, if any connection loosed, if the direction
is incorrect,…etc.).
2) Check if any short-circuit or defective peripherals by plugging out the power
connector from each peripheral, one at a time. Shall the system functions again,
you have solved the problem.
3) Once you hear the buzzer sound or see the warning LED in RED, please check,
a) If the loading is under the minimum or over the maximum load of each
channel.
b) If the power source is well connected and supplied.
Shall the above condition is happened, please disconnect the power source and
wait for 2-3 minutes to release the protection status; then test it again.
c) If buzzer keeps alarming or LED indicates the power module failure, please
locate which power module is defective. Perform hot-swap procedures (ref. to
Sec. 1.8 Hot-Swap Procedures). Return the defective power module back to
your vendor for RMA procedure.
d) If you can not fix the problem, please contact your vendor for supporting.
