Description

ICS TRIPLEX T8312-4
Trusted TMR Expander Processor
Product Overview
The Trusted® TMR Expander Processor Module resides in the processor slots of the Trusted
Expander Chassis and provides the ‘slave’ interface between the Expander Bus and the Expander
Chassis Backplane. The Expander Bus allows multiple chassis systems to be implemented using
Unshielded Twisted Pair (UTP) cable connections whilst maintaining the fault tolerant, high
bandwidth Inter-Module Bus (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.
