1.1 INTRODUCTION

First of all, thank you for purchasing MRW/MRP series redundant power supply.

The MRW/MRP series 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 MRW/MRP series hot swappable redundant power supply offer maximum

350/400/420 watts, and provide Active Power Factor correction (PFC) at full range AC

input that complaints to EN 61000-3-2 for CE norms. 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 6 outputs (+3.3V, +5V, +12V, -5V, -12V, and +5Vsb) circuits.

All you can see on the backplane is just passive components and this is the key point

for longer MTBF.

The units also offer a warning sub-system, including LED display, buzzer alarm, TTL

signal. It guides user the fast way to find out the power supply 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.

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.

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.
