4.0 INSTALLATION
This section describes the functions of the Model 1000R16P rack
chassis, tells how to install front and rear Model 2020RC cards into the
chassis and provides diagrams for wiring up the interface connections
correctly.
4.1 THE MODEL 1000R16P RACK CHASSIS
The 1000R16P Rack Chassis (shown in Figure 4, below) has
sixteen short range modem card slots, plus its own power supply.
Measuring only 3.5" high, the 100016RP is designed to occupy only 2U
in a 19" rack. Sturdy front handles allow the 1000R16P to be extracted
and transported conveniently.
4.1.1 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 spring loaded thumb screws and the
rear card by conventional metal screws.

Switching the Power Supply On and Off
The power 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.
NOTE:
Please refer to the Model 1000RP Series User Manual
AC
and DC Rack Mount Power Supplie
s for fuse and power card
replacement information.
4.2 INSTALLING THE MODEL 2020RC INTO THE CHASSIS
The Model 2020RC is comprised of a front Function card and a
rear Interface card. The two cards connect in the rack chassis via
mating 50 pin card edge connectors. Use the following steps as a
guideline for installing each Model 2020RC into the Model 1000R16P
rack chassis:
1.
Slide the rear Interface card into the back of the chassis along the
metal rails.
2.
Secure the rear card using the metal screws provided.
3.
Slide the Function card into the front of the chassis. It should
meet the rear card when it's almost all the way into the

Notice!
Any terminal cable connected to the Model
2020RC must be shielded cable, and the outer shield must
be 360 degree bonded–at both ends–to a metal or
metalized backshell.
