1.1 INTRODUCTION
First of all, thank you for purchasing R2Z series redundant power supply.
The R2Z 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
It is composed of 1+1 pieces power modules. The number 1+1 stands for there is an
extra power module to backup the system if any power module fails.
The R2Z series offer a maximum 350 / 400 watts output power. The power module is
in compact size with high density, and built-in a 38 x 28mm ball bearing DC fan for
better ventilation and reliability. 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 R2Z series also offer a warning sub-system, including LED display, buzzer alarm,
TTL signal, and I2C interface device (available for R2W series as optional). 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
