EIO is the port for the network card on the back of the machine turn off machine remove card from EIO2 and install into EIO1 turn machine on and see what happens. If this does not work then open the formatter casing and remove the memory chips (OF COURSE WHEN THE MACHINE IS OFF) after removingone turn machine on and see if it boots up.
The 49 error is normally a software issue with the machine and it has locked within the network area or the memory.
Hope this helps you and please rate me

Hi there you both may have the power board blown the only way to check is plug in a new power cord if this doesn't work then will have to find a repair station.
Hope the cable works though
Please rate me
