5. Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No link on SFP ports | Transceiver or fiber | High | Verify compatible SFP/SFP+ and clean connectors | Use approved transceivers; check show interfaces |
| Stack members not visible | Stacking cable issue | High | Inspect stack cables and show stack status | Reseat cables; verify stack master election |
| High latency or drops | Routing or QoS config | Medium | Check CPU and buffer statistics | Tune QoS policies or review routing table |
| No 10Gb uplink | Speed negotiation | Medium | Confirm SFP+ module and peer device | Test with known-good 10Gb link |
| Management unreachable | IP or VLAN misconfig | Medium | Console access and show running-config | Verify management interface settings |
| Fan or power alarms | Overheating or PSU | Low | Monitor show environment | Improve airflow; check redundant power |

6. Frequently Asked Questions (FAQ)
What transceiver types does the C5K175-24 support? It accepts standard 1Gb SFP for the 24 ports and 10Gb SFP+ for the uplinks. Use Enterasys/Extreme qualified optics for best compatibility.
Is this switch stackable? Yes, with dedicated high-speed stacking ports that allow multiple C5 units to operate as a single logical switch.
Does it include Layer 3 routing? Yes, the C5K175-24 provides hardware-based Layer 3 switching and routing features suitable for distribution or core roles.
Can I add redundant power? It supports optional redundant power supplies for increased uptime in mission-critical setups.
How do I manage a stack? Access the entire stack through a single IP address on the master unit using CLI, web interface, or SNMP.
What condition are the units? New Original / New Surplus. Switches receive full port testing, SFP validation, stacking checks, and burn-in. Test reports and photos available on request.
Will this replace older C-Series models? It fits well as an upgrade within the C5 family. Check port types (SFP vs copper), software version, and stacking compatibility before migration. Document existing configs prior to replacement.
