Getting an error on starting a machine

I changed the PC addr. to 11, same behave as before, no succ.

yes to 10.10.10.11

The lack of yellow (100BT) LED illuminated the RJ45
suggests a problem with the 7I76E Ethernet interface
or the host Ethernet interface.

I would try a known working  Ethernet connection, and if you
do not get both Green (activity) and Yellow (100BT) LEDs
illuminated on the 7I76E RJ45 connection, I would return the
7I76E  for warranty repair. Note that especially for plasma systems
it's important to ground the frame ground connection on the 7I76E.

Thanks a lot for your afford.
