Patton electronic IM2RC/F Installation, THE MODEL 1000R16 RACK CHASSIS, The Rack Power Supply

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.

4.2INSTALLING 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.
