cFP-2220

Hi all, 

i have a cFP-2220 and after a network malfunction it stopped. I recovery it , from MAX , with IP RESET switch and reset it is restarted with a network interface Ip 0.0.0.0 and from max i set IP and its worked fine for 1 day. Now i have a same problem but with any procedure from manual i cant see it on MAX , the power led is green and the status led blink orange every 30s, has someone had the same problem? how i can undestand wath is wrong? 

Thanks!
