Appendix A Status Indicators
Module Status (MS) Indicator
These are the ControlNet module indicators.
IMPORTANT
Keep in mind that the Module Status indicator reflects the module state (for
example, self-test, firmware update, normal operation but no connection
established). The network status indicators, A and B, reflect network status.
Remember that the host is able to engage in local messaging with the card
although it is detached from the network. Therefore, the Module Status
indicator is flashing green if the host has successfully started the card. Note,
however, that until the host removes reset, all communication port status
indicators.
When you view the indicators, always view the Module Status indicator first to
determine the state of the communication port. This information may help you
to interpret the network indicators. As a general practice, view all indicators
(Module Status and Network Status) together to gain a full understanding of
the daughtercard’s status.
Indicator Condition Recommended Action
Off The controller has no power. Apply power.
The controller is faulted. Make sure that the controller is firmly seated in the slot.
Steady red A major fault has occurred on the controller. 1. Cycle power.
2. If the problem persists, replace the controller.
Flashing red A minor fault has occurred because a firmware update is in progress. Normal operation - No action is required.
A node address switch change has occurred. The controller’s node address
switches may have been changed since power-up.
Change the node address switches back to the original setting. The module
will continue to operate properly.
The controller uses invalid firmware. Update the controller firmware with the ControlFlash Update utility.
The controller’s node address duplicates that of another device. 1. Remove power.
2. Change the node address to a unique setting.
3. Reapply power.
Steady green Connections are established. Normal operation - No action is required.
Flashing green No connections are established. Establish connections, if necessary.
Flashing red/green The controller is diagnosing a problem. Wait briefly to see if problem corrects itself.
If problem persists, check the host. If the daughtercard cannot communicate
with the host, the card may remain in self-test mode.
