Status Indicator Description
OK status indicator Indicates the module’s current state.
Network channel status indicators Indicates the status of network channels A and B.
IMPORTANT
The OK status indicator reflects the module state, such as the running of
a self-test, the updating of firmware, and normal operation without an
established connection.
When you view the status indicators, always view the OK status
indicator first to determine the state of the module. This information may
help you to interpret the network channel status indicators. As a general
practice, view all status indicators together to gain a full understanding
of the module’s status.
