Symptom Possible Cause Relevance to this Part Quick Check Method Recommendation
PoE devices not powering Budget exceeded or port disabled ✅ High Run “show power inline” command Check total draw and enable ports
SFP+ ports no link Wrong optics or speed config ✅ High Verify “show interfaces” status Use compatible 1Gb/10Gb SFP+
Stacking issues Incompatible stack cable or member config ✅ Medium Check stack topology with CLI Use qualified stacking cables
High temperature Fan or airflow restriction ✅ Medium Monitor system sensors Ensure proper ventilation
No cloud connectivity Management VLAN or licensing ❌ Low Verify ExtremeCloud IQ config Confirm licensing and network reachability
Intermittent PoE Cable length or device classification ✅ High Test with short certified cable Confirm cable category and device PoE class
