T8311 ICS TRIPLEX T8311 TrustedTM TMR Expander Interface module T8311 ICS TRIPLEX T8311

ICS TRIPLEX T8311
The TrustedTM TMR Expander Interface module-T8311

The TrustedTM TMR Expander Interface module resides in the TrustedTM Controller Chassis and provides the ‘master’ interface between the Inter-Module Bus (IMB) in the Controller Chassis and the Expander Bus. 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 IMB in the Controller Chassis, ensuring that the effects of these potential faults are localised and system availability maximised. The module is fault tolerant with Hardware Implemented Fault Tolerant (HIFT), Triple Modular Redundant (TMR) architecture. Comprehensive diagnostics, monitoring and testing provide rapid fault identification. Hot standby and module sparing configurations are supported, allowing automatic and manual repair strategies.
