that the controller is functionin
.
If the controller is not functionin
, replace it. If neither the new controller nor the
Ethernet module will function, replace the backplane.
2.
Make sure that no more than two network option modules -- includin
NOE,
NOM, NOP and CRP 811 modules -- have been installed in the backplane with
a 140 CPU 113 or 213; no more than six network option modules with a 140
CPU 424, 434 or 534.
3.
Check the version of the controller executive. You must have version 1.1 or
