4.0 INSTALLATION
This section describes the functions of the Model 1001R14 rack
chassis, tells how to install front and rear Model 1092ARC Series cards
into the chassis, and how to connect to the twisted pair interface and
the serial interface.
4.1 THE MODEL 1001R14 RACK CHASSIS
The Model 1001R14 Rack Chassis (Figure 9, below) has 16 card
slots, plus its own power supply. Measuring only 3.5” high, the Model
1001R14 is designed to occupy only 2U in a 19” rack. Sturdy front
handles allow the Model 1001R14 to be extracted and transported
conveniently.
4.1.1 The Rack Power Supply
The power supply included in the Model 1001R14 rack 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 thumb screws and the rear card by
conventional metal screws.
