4.0 INSTALLATION
This section describes the functions of the Model 1000R16 rack
chassis, tells how to install the rear-mounted Model IM2RC/F card into
the chassis, and how to connect to the G.703 PCM network, and to the
twisted pair line interface. Please refer to the appropriate function card
user manual for further details.
4.1 THE MODEL 1000R16 RACK CHASSIS
The Model 1000R16 Rack Chassis (Figure 4, below) has sixteen
baseband 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 function cards. The front function
card and the power supply slide in from the front, while the rear card
and power entry modules slide 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.
WARNING!
There are no user-serviceable parts in the
power supply section. Voltage setting changes and fuse
replacement should only be performed by qualified
service personnel. Contact Patton Electronics Technical
support at (301)975-1007 for more information.

NOTE: Please refer to the Model 1000RP Series User Manual AC
and DC Rack Mount Power Supplies for fuse and power card
replacement information.
4.2 INSTALLING THE REAR IM2RC/F CARD AND FRONT
FUNCTION CARD
The Model IM2RC/F is a rear-mountable G.703 interface card that
works with Patton function card access products that support 64k/128k
synchronous data rates. 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 IM2RC/F and its function card mate into the rack chassis:
WARNING!
The IM2RC/F card contains sensitive
integrated circuitry. Failure to ground yourself during
installation may result in damage to the IM2RC/F card or
the front function card.
1.
Slide the IM2RC/F rear card into the back of the chassis along
the metal rails provided.
2.
Secure the IM2RC/F rear card using the metal screws
provided.
3.
Slide the front function card into the front of the chassis. It
should meet the IM2RC/F rear card when it is 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.
