CCR 1009 keeps booting

Hi,

I have upgraded CCR 1009 with firmware 6.43.4 and since then it keep rebooting. What might be the issue?
It remains ON if no LAN cable is attached, but as soon as I attach LAN cable to my PC, it gets reboot.

Hi Jam38

Have you tried to look at the lcd and see the error or status?
Or
Have you tried to connect to the CCR using the serial port?
