TMR Expander Processor
Introduction
The Trusted TM TMR Expander Processor module resides in the processor slots of the Trusted TM
Expander Chassis and provides the ‘slave’ interface between the Expansion Bus and the Expander
Chassis backplane. The Expander Bus allows multiple chassis systems to be implemented using UTP
cable connections whilst maintaining the fault tolerant, high bandwidth IMB capabilities.
The module provides fault containment for the expander bus, the module itself and the expander
chassis, ensuring that the effects of these potential faults are localised and system availability
maximised. The module is fault tolerant with HIFT TMR architecture. Comprehensive diagnostics,
monitoring and testing provide rapid fault identification. Hot standby and module spare configurations
are supported, allowing automatic and manual repair strategies.
Features
• Triple Modular Redundant (TMR), fault tolerant (3-2-0) operation
• Hardware Implemented Fault Tolerant (HIFT) architecture
• Dedicated hardware and software test regimes which provide very fast
fault recognition and response times
• Automatic fault handling without nuisance alarming
• Hot replacement
• Front panel indicators that show module health and status.
