System Chassis Overview

Main Chassis

• Power Supplies: Located on the left side, one above the other.

• Main Processors: Positioned immediately to the right of the power supplies.

• Slots for Modules:

  • Six logical slots for I/O and communication modules.
  • One COM slot with no hot-spare position.
  • Each logical slot includes two physical spaces for modules: one for the active module and one for its optional hot-spare module.

Expansion Chassis

• Layout: Similar to the main chassis.

• Slots for Modules:

  • Eight logical slots for I/O modules.
  • The spaces used by the main processors and the COM slot in the main chassis are available for other purposes.

Interconnection

• I/O Bus Cables: The main and expansion chassis are interconnected using triplicated I/O bus cables.

• Cable Length:

  • Standard maximum length: 100 feet (30 meters).
  • Extended length (restricted applications): Up to 1,000 feet (300 meters).
  • For configurations exceeding 30 meters, consult a Triconex Customer Support representative.

RXM Chassis

• Usage: For systems where the total cable distance between the first and last chassis exceeds the supportable distance by copper.

• RXM Modules: Each RXM chassis houses a set of three RXM modules in the same position as the main processors in the main chassis.

• Slots for Modules:

  • Six remaining logical slots.
  • One blank (unused) slot.
