Introduction

This part of GB/T 19520 provides the dimensions of miniaturized plug-in boxes and plug-ins, as well as the specified optional/miniaturized plug-ins.

New technologies that require the use of miniaturized plug-ins in 19in equipment are rapidly gaining acceptance.

Recognizing this development trend, common interface standards will obviously benefit the industry.

This part is based on the PCI Industrial Computer Manufacturers Organization (PICMG) developed by AMC.0 and MicroTCA.

The specifications of the pieces are coordinated.

Through the feasible key interface size and allow the use of the industry's optional connectors (other than AMC.0 and MicroTCA), a variety of

Product solutions can use this technology to increase overall market acceptance, increase availability, and cut costs.

In order to meet the requirements of miniaturized plug-ins in the subrack, this section specifies these miniaturized interface sizes.

The miniaturized universal size is based on and coordinated with AMC.0 and MicroTCA.

Since the AMC.0 and MicroTCA specifications only specify a limited range of connectors, this section shows the use of other applicable connectors

Possibility.
