T9901

|Rated 5.0

The Expander Bus enables the implementation of multiple chassis systems using UTP cable connections, while maintaining the fault-tolerant, high-bandwidth capabilities of the Inter-Module Bus (IMB). The Control card, which resides in the Trusted™ Controller Chassis, acts as the ‘master’ interface between the IMB in the Controller Chassis and the Expander Bus. This module ensures fault containment for the Expander Bus, the module itself, and the IMB, effectively localizing any potential faults and maximizing system availability. Designed with HIFT TMR architecture, it offers fault tolerance, along with comprehensive diagnostics, monitoring, and testing features that provide rapid fault identification and efficient troubleshooting.

FAQ
1. What is the function of the T9901 module?
The T9901 provides the master interface between the IMB in the controller chassis and the Expander Bus, enabling the expansion of the system. It also ensures fault containment for the Expander Bus, module, and IMB, localizing faults and optimizing system availability.

2. What architecture does the T9901 module use?
The T9901 is built using HIFT TMR (Triple Modular Redundancy) architecture, ensuring fault tolerance for critical system components.

3. How does the T9901 help with system availability?
By localizing potential faults within the Expander Bus, the module prevents issues from spreading to other parts of the system. This fault containment helps maximize overall system availability and reliability.
