Working Principle
The T8314 module interfaces between the main Trusted chassis and remote expander chassis. It converts electrical backplane signals into optical signals for transmission over single-mode fiber. At the remote end, a corresponding T8314 converts the optical signals back to electrical signals for the expander chassis backplane. Triple redundant data paths ensure that communication integrity is maintained even if one path experiences a fault. Continuous diagnostic monitoring verifies link health and reports any communication errors.
Installation Requirements
- Install in designated Trusted rack slots at both main and remote chassis
- Use qualified single-mode fiber optic cable with SC connectors
- Ensure proper fiber handling to prevent damage or contamination
- Verify system power meets specifications before installation
- Maintain bend radius requirements for fiber optic cables
Operating Precautions
- Inspect fiber connectors regularly for cleanliness and damage
- Monitor link status LEDs for communication fault indication
- Avoid exceeding the maximum fiber bend radius
- Protect fiber cables from physical damage and crushing
- Maintain spare modules for rapid replacement of failed units
