4.1.2 Non-Scrolling LED Status Indicators
The non-scrolling LEDs indicate the module’s operating status as follows:
LED Label
Status
Indication
APP
OFF
The module is not receiving adequate power or is not securely plugged
into the rack. May also be OFF during configuration download.
GREEN
The MVI56E-MNETC/MNETCXT is working normally.
RED
The most common cause is that the module has detected a
communication error during operation of an application port.
The following conditions may also cause a RED LED:
 The firmware is initializing during startup
 The firmware detects an on-board hardware problem during startup
 Failure of application port hardware during startup
 The module is shutting down
 The module is rebooting due to a ColdBoot or WarmBoot request
from the ladder logic or Debug Menu
OK
OFF
The module is not receiving adequate power or is not securely plugged
into the rack.
GREEN
The module is operating normally.
RED
The module has detected an internal error or is being initialized. If the
LED remains RED for over 10 seconds, the module is not working.
Remove it from the rack and re-insert it to restart its internal program.
ERR
RED
Not used.
4.2 Clearing a Fault Condition
Typically, if the OK LED on the front of the module remains RED for more than
ten seconds, a hardware problem has been detected or the program has exited.
To clear the condition, follow these steps:
1 Turn off power to the rack.
2 Remove the card from the rack.
3 Verify that all jumpers are set correctly.
4 If the module requires a Compact Flash card, verify it is installed correctly.
5 Re-insert the card in the rack and turn the power back on.
6 Verify correct configuration data is being transferred to the module from the
ControlLogix controller.
If the module's OK LED does not turn GREEN, verify that the module is inserted
completely into the rack. If this does not cure the problem, contact ProSoft
Technology Technical Support.
