5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No link on SFP ports | Transceiver or fiber issue | High | Check show interfaces and transceiver status | Verify compatible SFP, clean fiber ends |
| Module not recognized | Slot seating or chassis issue | High | Run show module or slot status | Reseat module and check control module logs |
| Link flaps or errors | Dirty connectors or bad SFP | High | Monitor port statistics | Clean or replace individual SFP |
| Speed negotiation failure | Auto-negotiation mismatch | Medium | Check configured speed/duplex | Set matching parameters on connected device |
| High CPU on control plane | Configuration or broadcast storm | Low | Review show process cpu | Filter traffic or tune STP/IGMP settings |
Provide chassis diagnostics and port logs to support if the module itself appears faulty after transceiver validation.
6. Frequently Asked Questions (FAQ)
Is the EC8404007-E6 hot-swappable? Yes. These I/O modules support hot insertion/removal in the VSP 8400 chassis. Drain traffic from the ports before swapping when possible.
What SFPs are compatible? It supports standard 1000BASE-SX, 1000BASE-LX, and other Extreme-qualified 1G SFPs. Always check the VSP 8400 compatibility list for your VOSS software version.
Can this module do 100 Mbps and 1 Gbps? Yes, each port auto-negotiates or can be manually configured for 100 Mbps or 1 Gbps fiber links.
Is this module still supported? The VSP 8400 platform is mature. New surplus stock is tested on a VSP 8400 chassis and includes a 1-year warranty.
How many ports can one chassis support? Depending on the VSP 8400 model and slot configuration, multiple modules allow scaling to dozens of 1G fiber ports.
Do I need to buy transceivers separately? Yes. SFPs are not included. We can help recommend compatible part numbers based on your distance and fiber type requirements.
What is the difference between this and copper versions? This EC8404007-E6 uses SFP slots for fiber connectivity. Copper variants use RJ45 ports. Choose based on your cabling infrastructure.
