When the board was powered from the ethernet port: none of the leds blink or start up. On several tries, all the leds blink and no start up the board... (the power supply seems to be ok, It powered a 532A without problems).

When the board was powered from the dc jack: It runs without problems... (Same power supply).

Power supply, 48v 1A, setup (XR5, SR2, RH52)
There is any issue about powering???, or some rule about to take on mind before...?????
Comments....???
