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.
2.
Replace and return the fault
y
 Ethernet web embedded server module.
