I have a bunch of 5340 sets in stock. I was just doing a power and display test using a POE switch. All LEDs come up for a couple seconds then they go off and then the display shows the startup routine. On two of the sets none of the LEDs come at all but the display does show the startup routine. I've seen this happen several times when testing various IP set types but after connecting and disconnecting them from the POE a couple of times, the LEDs always come on for a few seconds. Can anyone confirm that hese sets are defective?
