Kernel loading failed and ethernet cable abset while upgrade

Hi…

I have a routerboard 1100 X2 AH.While I am trying to upgrade the firmware using netinstall,it is showing error while I connect the ethernet cable to any of the ports from ether1 to ether 10 as:

Check the ethernet cable…
Ethernet cable is absent…

While I am trying to upgrade the firmware through ether 11 to ether 13, it is showing the error as:

Kernel loading failed…

Otherwise the router is working normally.It is booting fine with NAND only.
