ASYNC 232↔422/530 CARD
This chapter describes the functions of the MicroRacks, tells how to install
front and rear Async 232↔422/530 Cards in the chassis, and provides
diagrams for wiring the interface connections correctly.
4.1 The MicroRack Chassis
The MicroRack 16 has sixteen short-range modem card slots, plus its own
power supply. Measuring only 3.5 inches high, the MicroRack is designed to
occupy only 2U in a 19-inch rack. Sturdy front handles allow the MicroRack
16 to be extracted and transported conveniently.
Figure 4-1. The MicroRack 16 with power supply.
The power supply used in the MicroRack 16 uses the same mid-plane
architecture as the modem cards. The front card of the power supply slides
in from the front, and the rear card slides in from the rear. They plug into
one another in the middle of the rack. The front card is then secured by
thumbscrews and the rear card by conventional metal screws.
