6.2.3. Hardware Issues

PoE (Power over Ethernet) Issues:
  • Budget exceeded: Total device power needs exceed switch PoE capacity
  • Standard mismatch: Device expects PoE+ (30W), switch provides PoE (15.4W)
Transceiver Issues:
  • Mismatch: Different speeds, wavelengths, or fiber types
  • Low light levels: Check with optical power meter
  • Dirty connectors: Clean fiber end faces
