MULTI-FUNCTION LD CARD

4. Installation

This chapter describes the functions of the MicroRacks, tells how to install the front and rear modules of the Multi-Function LD Cards in them, and provides diagrams for wiring the interface connections correctly.

4.1 The MicroRacks: An Overview

Multi-Function LD Cards are designed to be installed in our MicroRacks (product codes RM202 for the 2-card models, RM204 for the 4-card models, RM208 for the 8-card models, and RM216 for the 16-card models). You will install Multi-Function LD Cards in any MicroRack the same way.

As an example of these products, the MicroRack 16, shown in Figure 4-1 below, features sixteen slots for short-range modem cards, plus its own power supply. Measuring only 3.5" (8.9 cm) high, the MicroRack 16 is designed to occupy only 2U in a 19" rack. Sturdy front handles allow the MicroRack 16 to be extracted and transported conveniently.

Multi-Function LD Cards installed).
