Example: The Ether register access error detection.
No abnormality was detected.
An abnormality was detected in communication between the EEPROM of main
P.C.B. and IC.
Check the digital P.C.B. and main P.C.B. connection connector.
If there is no problem, malfunction in the main P.C.B. is suspected.
Since a communication failure occurred between CPU and ETHER-LSI as well,
there is a high possibility of digital P.C.B. circuit (such as foil cutting) or parts fail-
ure.
Replace the Digital P.C.B..
A communication failure occurred between EEPROM of main P.C.B. and CPU,
CPU and ETHER-LSI.
Take measures for "2" and "4".
The Input Code is not correct. Please check the Diagnosis Code again.
