6.1.2 Active LED
If the
Active
LED fails to li
g
ht, the module is not communicatin
g
with the
backplane.
Troubleshooting 1.
Make sure the Ethernet web embedded server module and the controller are
installed properl
y
. Verif
y
that the controller is functionin
g
.
If the controller is not functionin
g
, 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
g
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
g
reater to support the Ethernet web embedded server module. Earlier versions
do not reco
g
nize the module.
4.
Replace and return the fault
y
Ethernet web embedded server module.
6.1.3 Ready LED
If the
Ready
LED fails to li
g
ht, the module has failed internal dia
g
nostic tests.
Troubleshooting 1.
Make sure that power has been applied to the backplane.
