Zippy DMRW-6400F User Manual

1.1 INTRODUCTION

First of all, thank you for purchasing DMRW series redundant power supply.

The DMRW 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 DMRW series hot swappable redundant power supply offer maximum
300/350/375/400 watts. 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.

1.2 PACKING

Your DMRW series should consist of the following,

a) DMRW series x 1
b) Accessory pack x 1
c) Product Manual x 1
