The T9401 module is designed to enhance system reliability by enabling multiple chassis systems to connect via UTP cables while retaining the fault-tolerant, high-bandwidth capabilities of the IMB. Utilizing a fault-tolerant HIFT TMR architecture, the module features comprehensive diagnostics, monitoring, and testing for rapid fault identification. It ensures fault containment for the Expander Bus, the module itself, and the IMB in the Controller Chassis, localizing potential faults to maximize system availability. Additionally, the module supports hot standby and spare slot configurations, facilitating both automatic and manual repair strategies to maintain operational efficiency.

Frequently Asked Questions (FAQ): T9401 Module
1. What is the primary function of the T9401 module?
The T9401 module connects multiple chassis systems via UTP cables while maintaining the fault-tolerant and high-bandwidth capabilities of the IMB.

2. What architecture does the T9401 module use?
The T9401 utilizes a fault-tolerant HIFT TMR (Triple Modular Redundancy) architecture, ensuring high reliability and system resilience.

3. How does the T9401 handle faults?
The module provides comprehensive diagnostics, monitoring, and testing to quickly identify faults. It also includes fault containment mechanisms for the Expander Bus, the module itself, and the IMB in the Controller Chassis, ensuring that faults are localized and do not affect the entire system.
