4.0 INSTALLATION
This section describes the functions of the Model 1000R16P rack chas-
sis, tells how to install front and rear Model 1080ARC cards into the
chassis, and provides diagrams for wiring the interface connections cor-
rectly.
4.1 THE MODEL 1000R16P RACK CHASSIS
The Model 1000R16P Rack Chassis (Figure 7) has sixteen short range
modem card slots, plus its own power supply. Measuring only 3.5” high,
the Model 1000R16P is designed to occupy only 2U in a 19” rack.
Sturdy front handles allow the Model 1000R16P to be extracted and
transported conveniently.
The Rack Power Supply
The power supply included in the Model 1000R16P 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.

Switching the Power Supply On and Off
The power supply on/off switch is located on the front panel. When
plugged in and switched on, a red front panel LED will glow. Since the
Model 1000R16P is a “hot swappable” rack, it is not necessary for any
cards to be installed before switching on the power supply. The power
supply may be switched off at any time without harming the installed
cards. Be sure power is off before power module card is removed.
