Working Principle The T8311 installs in single-width slots in the controller chassis, with dual modules placed in left-hand odd-numbered slots. The TMR processor automatically selects the active module. It manages communication between the controller chassis backplane and expansion chassis processors via the 250 Mbps expander bus, maintaining data integrity through triplicated paths and voting logic.
Installation Requirements
- Install in controller chassis slots only
- Use TC-301 copper cable or fiber converters for expansion bus
- Configure dual modules in left-hand odd-numbered slots
- Ensure redundant power connections from controller chassis
- Verify T8300 chassis compatibility
Operating Precautions
- Monitor Healthy LED for green steady indication, red flashing indicates fault
- Verify Active LED shows green steady when module is primary
- Check Standby LED shows green steady in standby mode
- Replace faulted modules showing persistent red indicators
- Maintain cable connections to prevent communication interruptions
