  • Page 11: Module Description

    MODULE DESCRIPTION Section 2 2.1 GENERAL DESCRIPTION The Dual Node Module is a chassis containing one or two nodes. Each node performs an independent function and occupies a specific address on the Local Control Network (LCN). Figure 2-1 shows the module functions within a typical TDC 3000 X System. The types of nodes available in the Dual Node Module include Application Modules, Network Interface Modules, History Modules, Universal Stations, Hiway Gateways, and other types of gateways.

    2.4 FRONT PANEL The module front panel has the necessary windows and switch openings to accommodate two nodes in a single module. Figure 2-3 shows the front panel for the Dual Node Module. For each of the two power supplies, there are openings for the POWER switch and RESET switch and a window to view the light-emitting diode (LED) status indicators.

    2.5 REAR PANEL ASSEMBLY The Rear Panel Assembly includes the Backpanel Printed Wire Assembly (PWA) and the Input/Output (I/O) Card Cage Assembly. The power supplies, the fan assembly and the main circuit boards (such as the K2LCN OR K4LCN) all plug into card edge connectors on the front side of the Backpanel PWA.
  • Page 27: Field Adjustments

    2.7 FIELD ADJUSTMENTS There are no field adjustments for the Dual Node Module. However, the K2LCN must be pinned for the particular node address it occupies on the LCN. Figure 2-4 shows the pinning options for the K2LCN. The EPDGC-(I/O) board, if present, has pinning options to set the default background shade for the CRT if a palette has not been set in a schematic (Set Palette is a new command in Release 320).

  • Page 67 REPLACEMENT OF K2LCN WITH K4LCN Appendix B This appendix gives the procedure for replacing an K2LCN processor with a K4LCN. It also gives the restrictions and conditions that apply to the replacement procedure. B.1 INTRODUCTION This procedure enables a trained technician to replace an K2LCN processor board with a high density 68040-based K4LCN processor board in a Five-Slot or Ten-Slot Module LCN node.
  • Page 68 B.2 RESTRICTIONS TO TOTAL REPLACEMENT If you are contemplating the replacement of all K4LCN processors in Five/Ten-Slot Modules, be aware that the Clock Source/Repeater board is the single point ground connection for the LCN cable shield. Therefore, even if the 12.5 kHz (Subchannel) clock function is not being used, a CS/R or other grounding means is still required on each coax segment.
  • Page 69 B.6 REDUNDANT MODULE REPLACEMENTS 1. This section applies only to a redundant Network Interface Module (NIM), Hiway Gateway (HG), or Programmable Logic Controller Gateway (PLCG). 2. Determine in which unit, the primary or secondary, you want to perform the replacement first. The recommended procedure would have you replace the processor in the primary unit first.
