I have two ICX 6450 24P switches at my garage. They run PoE for VoIP, Access Control and Cameras. I had a report that the cameras were no longer working. When I looked at the Inline Power the first time it showed various Power Issues so I rebooted the switch. After they came back up it showed that ports 1/1/2-1/1/13 were receiving 30000 mWatts and nothing else was available for allocation. The phones were still working but the cameras (1/1/19 - 1/1/22) were not. I then did a firmware update on them and now I show 0 Consumed or Allocated on both switches. Again, phones working, cameras not. Currently, I have injectors for the cameras and they are fine. Just not sure why I am getting the errors.
(apologies to folks for reviving an ancient thread)
@BenBeck - I recently replaced a Ubiquiti ES-24-250W with a "new to me" ICX 6450-24P, and suddenly my attached Netgear GS105PE (5-port Class 4 PoE-powered) switches started intermittently falling off the network.
Dropping the manual "power-limit" / "power-by-class", followed by adding "lldp run" to the global configuration on the ICX 6450-24P solved the problem - all five of my GS105PEs are acting normally again.
