Zippy GIH4-6950P User Manual

1.1 INTRODUCTION

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

The GIHn series is a N+1 hot-swappable / hot-pluggable redundant power supply. It
consists of,

1) complete metal frame

2) compact size power module

3) backplane

It is composed of N+1 pieces power modules. The number N+1 stands for there is an
extra power module to backup the system if any power module fails.

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, and compliant to ATX12V / EPS12V. All you can see on
the backplane is just passive components and this is the key point for longer MTBF.

The GIHn series offer a warning sub-system, including LED display, buzzer alarm,
TTL signal, and I2C interface device (optional). 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.

1.2 PACKING
