3.2.1   HOW THE JUMPER WORKS

Figure 4 (below) shows the 3-pin jumpers used on the rear card.

The strap enables or disables a particular function depending upon
whether it straddles pins 1 and 2, or pins 2 and 3.  

DTE Shield (Pin 1) & FRGND (JB1)

In the connected (closed) position, this strap links DB-25 pin 1 and

frame ground.  In the open (disconnected) position, pin 1 is “lifted” from
frame ground.

4.0  INSTALLATION

This section describes the functions of the Model 1000R16 rack

chassis, tells how to install front and rear Model 1140RC cards into the
chassis, and provides instructions for connecting the interface cables.

4.1  THE MODEL 1000R16 RACK CHASSIS

The 1000R16 Rack Chassis (Figure 5, below) has sixteen short

range modem card slots, plus its own power supply.  Measuring only
3.5” high, the 1000R16 is designed to occupy only 2U in a 19” rack.
Sturdy front handles allow the 1000R16 to be extracted and transported
conveniently.

4.1.1  THE RACK POWER SUPPLY

The power supply included in the Model 1000R16 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.
