Patton electronic Model 1000R16 Rack Chassis, Rack Power Supply, Wiring the Model 1018RC

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.

WARNING! There are no user-serviceable parts in the power supply section of the Model 1018RC. Voltage setting changes and fuse replacement should only be performed by qualified service personnel. Contact Patton Electronics Technical support at (301)975-1007, http://www.patton.com, or support@patton.com for more information.

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.
