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 1000R16 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.
4.2 INSTALLING THE MODEL 1018RC INTO THE CHASSIS
The Model 1018RC is comprised of a front card and a rear card.
The two cards meet inside the rack chassis and plug into each other by
way of mating 50 pin card edge connectors. Use the following steps as
a guideline for installing each Model 1018RC into the rack chassis:
1.
Slide the rear card into the back of the chassis along the metal
rails provided.
2.
Secure the rear card using the metal screws provided.
3.
Slide the card into the front of the chassis. It should meet the
rear card when it’s almost all the way into the chassis.
4.
Push the front card
gently into the card-edge receptacle of the
rear card. It should “click” into place.
5.
Secure the front card using the thumb screws.
Note: Since the Model 1018RC16P chassis allows “hot swapping”
of cards, it is not necessary to power down the rack when
you install or remove a Model 1018RC.
4.3 WIRING THE MODEL 1018RC
Each of the rear interface cards compatible with the Model 1018RC
has one terminal interface port and one 4-wire (twisted pair) port.
These cards provide a female DB-25 for the terminal interface
connection.

4.0 INSTALLATION
This section describes the functions of the Model 1000R16 rack
chassis, tells how to install front and rear Model 1018RC cards into the
chassis, and provides diagrams for wiring the interface connections
correctly.
4.1 THE MODEL 1000R16 RACK CHASSIS
The Model 1000R16 Rack Chassis (Figure 9) has sixteen short
range modem card slots, plus its own power supply. Measuring only
3.5” high, the Model 1000R16 is designed to occupy only 2U in a 19”
rack. Sturdy front handles allow the Model 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.
