The Woodward 5453-279 MicroNet TMR Chassis is a central hub designed for critical components like power supplies, CPUs, and I/O modules. It supports TMR (Triple Modular Redundant) systems, ensuring high reliability and fault tolerance.

Key Features

The chassis accommodates various elements, including:

• Power Supplies: Dedicated slots for kernel power supplies, essential for providing system power.
• CPUs: Slots for central processing units (CPUs), which execute critical system tasks.
• I/O Modules: The chassis can hold up to twelve I/O modules, enabling communication with external devices and sensors.

Processor Configurations

The system’s expansion depends on the type of CPU used:

• TMR5200 Processors: These processors enable I/O sharing through RTN networks. The system can expand to include up to three I/O chassis.
• TMR040 Processors: These processors establish dedicated I/O connections through transceivers and cables, ensuring each CPU has exclusive access to its I/O resources.

Expansion Capabilities

• With TMR5200 processors, the system can share I/O modules across CPUs using RTN networks.
• In contrast, TMR040 processors require transceivers and cables to connect I/O resources to specific CPUs.
